Many improvements, bug fixes

*: Allow math functions to be enabled via configure
*: Allow support for references to be removed
*: Documentation updates
*: Jim_ListLength() now returns the result directly
*: Optimise list -> dict conversion
*: Consistent capitalisation of some structures, functions
*: Add support for abbreviations to Jim_GetEnum()
*: The commands to 'info' may be abbreviated
*: Use abbreviation support in parsing options to 'subst'
*: Use Jim_GetEnum() to parse return code names
*: Optimise 'array get', 'array set' if no conversion needed
*: Import Tcl string.test
*: string compare now returns -1,0,1 like Tcl
*: Fix 'string last' with index=0
*: Add support for 'string reverse'
*: Add -nocase option to 'string equal'
*: Fix infinite loop in 'string repeat str -1'
*: Support braced patterns in glob
*: glob should not return dot files unless the pattern starts with .
*: Simplify glob.tcl by using some new features
*: When creating C extensions from Tcl, preserve newlines and invoke
   with Jim_Eval_Named() to produce more meaningful error messages.
*: Also remove all comments, not just those starting in the first column
*: Add support for 'n+n' and 'n-n' in string/list indexes (Tcl 8.5)
*: Add a level to the stack trace for 'return -code error'
*: 'return -code' should also affect the return from 'source' (see Tcl docs)
*: Fix lsort -command
*: Some systems don't have INFINITY
