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.

Removed completed TODO.

Changed RenderDescription method of TSnippetDoc to have a IActiveText instead of string parameter.
Made minimal changes to sub classes in order to compile and work reasonably effectively.

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.

XMLDoc commented units.

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
