CodeSnip Old Code (SVN)

Simplified and optimised TAlphaGrouping.Populate method. Now scans list of snippets list once rather than twice.

* Renamed UAlphabet unit as UInitialLetter and completely rewrote and simplified it.
* Modified units using UInitialLetter unit as necessary re changes.
* Modified TAlphaGroupItem and TAlphaGrouping to accept any upper case Unicode character instead of just "A".."Z" and "_". Uses natural sorting so, for example "Ö" sorts between "O" and "P". Now scans all snippets to build list of initial letters.

* Completely rewrote and greatly simplified USnippetKindInfo unit.
* Modified using units as necessary.
* Got rid of some more FreeAndNil calls.

Development branch for CodeSnip release 4.

Initial source is a copy of v3.8.4 (r1075).
