Official TkDiff Version 5.6 Released

This is a minor stabilizing release, primarily one fix and one new feature. The new feature enables possible directory recursion in the case where ONLY a single directory was provided as input (and thus expects the SCM to provide the file to compare with). While not something that most SCM usage has a need for, the Vpath SCM can require this if the organization of the files happens to be a tree. Nevertheless, it will work for other SCMs, but will DO so by enumerating every file that can be found in its sandbox - potentially a VERY large number of candidates - unlike the input case of TWO directories (which generally weeds out pairings with no changes)! Naturally, the Help information has been adjusted as well to account for all of this.

Additionally, an important issue concerning the optional "Merge Preview" window failing to respond to every jump-scroll request (and complaining it resulted from a TK error) was also repaired and bundled as well. Naturally, a handful of random typo errors (in Help and elsewhere) not affecting operational outcomes are also present.

Lastly, this release represents the zenith of anticipated changes. Until such time as we identify some missing feature (or our community locates some oversight) we expect this release to simply BE the successor of record.
