Improve stack trace handling

*: Get rid of JIM_ERR_ADDSTACK and use interp->addStackTrace instead
*: 'return -code error' doesn't add a stack frame
*: Rename _file_copy to {file copy} for better error messages
*: Use 'return -code' to prevent excessive levels in the stack trace
Also rename info_nameofexecutable to {info nameofexecutable}
