Compare Tools (Revision #5)

Editor Difference Pane now includes these new features:

• Includes visual indicators to match changes from one editor to the other - new style difference display with visual alignment using splines
• Line numbers are shown in the center divider, also shows current change and the number of changes X/X
• Annotation bar next to the vertical scroll bar shows bird’s eye view of the changes
• Toolbar now has an option button - compare options button on the diff panel ... which now also includes - color selection (added, deleted, changed)
• Shows the character differences in a modified line - highlight individual changes (words, characters) within modified block
• Save AS HTML ... new diff preview in the HTML differences of a specific file - save to html button produces highlights change within modified block

Schema and Script tree now feature 'Compare' popup menu option, which allows for diffing two files, directories, or schema tree nodes.

TBD: we need to define what happens when two schema tree nodes are being compared.  What happens when disparate nodes are selected?  Perhaps even allow to compare a file to a schema node (its DDL?)
