Continuing development on WB-628 - Ability to adjust NIFTI form dynamically in wb_view: Added 'image' toolbar for editing of control points (add, delete, delete all); added selection of image control points; moved conversion of image to volume from Data Menu to image toolbar; and other related items.

Added display properties for image display.  The properties include: Depth of image (behind, in front, or in middle of model), minimum and maximum thresholds, and opacity.

Fixed bug that mixed up a property for the tab with corresponding property for the display group for the standard color type.

Fixing drawing of orthogonal volume slices in ALL view so that they are drawing correctly for any orientation.  Again this is for ALL view (note that volume slice view was previously corrected by Tim).

make -cifti-merge-dense do something reasonable with volume label data - currently the later arguments get priority for position in the label table, due to replace structure

Resolve WB-646 - Colorers fail to display trailing zeros when set to a manual precision: On Overlay and Map Settings Dialog, when Numeric Format is Decimal or Scientific, the number of digits (even all zeros) right of the decimal point when drawing color bar is always the value from the Dec/Sci Decimals spin box.

If a dense dynamic file was enabled in overlay but not enabled for loading of connectivity data AND no loading had been performed, the identication window listed the dynamic connectivity file but without any values.  This has been corrected to not show the file if no data values are available.  Thus, dynamic connectivity data values are listed in the if and only if the dynamic connectivity files is selected as a layer in the connectivity tab and data is available.

Closes #19

updates to src/debian/copyright

small hack to make disabling the dynconn layer prevent the computation and show empty string in identification window

Implement WB-633 : New requirements for updating of connectivity data: (1) A second checkbox that enables dynamic connectivity has been added to Overlay Toolbox --> Connectivity.  Dynamic connectivity files are only available in the Overlay --> Layers section if this checkbox is checked; (2) Checkbox labeled "On" has been changed to "Load" on Overlay --> Toolbox; (3) A preference has been added for enabling dynamic connectivity data from data-series file on Preferences Misc tab; (4) Old scenes will default to dynamic connectivity on.  Name of dynamic connectivity file in Overlay --> Layers and Overlay --> Connectivity is now prefixed with "dynconn".

Resolve WB-643: Loading a scene causes contained files to default to "in spec":  The "in spec" status is now preserved when loading a scene.  The name of the spec file within the scene must match the name of the current spec file and the data files are matched using their absolute paths.

Resolve WB-644: Timecourse on/off status from charts not saved to scenes: Restoration of the chart selection status has been fixed.

Resolve WB-642 Adjusting the color bar position by typing or arrows does not work.  When annotation color bar placement is Automatic, any requests to change color bar's position were ignored.  Now, if the user attempts to move the color bar, change the color bar's positioning mode from Automatic to Manual so that the color bar will move.

Resolve WB-641 Overlay and map settings dialog precision issue: In the statistics section of the dialog, the width was fixed for the numeric characters so there was insufficient space when the values were large and clipped at the left side.  The space for the values will now shrink and expand as needed so that the numeric values are fully visible.

set all of pixdim[] to 1 by default, doesn't change our warnings, better nifti conformance, reduces warnings from other software

Resolve WB-639: (Forgot to add ZipSceneFileDialog to repository before committing) Added Zip Scene File Dialog for zipping a a scene file and its data files.  Dialog is launched using new "Zip" button on the Scene File Dialog.

Changed caret preferences: The default image capture type is 'render pixmap' which uses an offscreen pixmap for creating the image.  However, Linux systems have problems with the 'render pixmap' so the default for Linux has been changed to 'grab framebuffer'.  This change will only affect new users who have not run Workbench and thus do not yet have a preferences file.

Corrected VolumeFile::isMappedWithRGBA().  It was incorrectly returning true for any volume file type.

For copying of annotations between files, added option to copy only annotations that are selected in the window.
