CodeSnip Old Code (SVN)

Renamed UActiveText, UActiveTextHTML, UActiveTextRTF & UActiveTextValidator units into ActiveText namespace as UMain, UHTMLRenderer, URTFRenderer and UValidator respectively.
Updated all using units as necessary.

Changed TSnippet.Description property from string to IActiveText.
Made minimal changes to other calling code to work with new property type. Most of these take a simplistic approach and / or don't work correctly and need urgent attention.

This commit only seeks to have code compiling correctly after change.

Added new "class" snippet type for class and advanced record types.

Added new "units" snippet type.

Standardised svn:mime-type properties to "text/pascal" and svn:eol-style to "native"

Reintegrated v4-dev branch into trunk.
Trunk now contains v4 development tree

Updated snippets validator to reject snippet names that do not begin with 'A'..'Z', 'a'..'z' or an underscore. This fixes bug #3120958 for new and edited snippets.

Updated with changes merged from new-backend branch r709 and r1051 (r1051 used to resolve conflict due to renaming of FmUserDBEditDlg unit as FmSnippetsEditorDlg):
* Renamed TRoutineData, TRoutineReferences and TRoutineEditData as TSnippetData, TSnippetReferences and TSnippetEditData respectively.

Added an additional out parameter to several methods of TSnippetValidator that pass back information about the selection that could be used to highlight any errors. Modified code accordingly.

Corrected comment that said validator raises exception when it does not.
