CodeSnip Old Code (SVN)

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.

Modified extra text editor so that multiple paragraphs of text can be entered without using REML mark-up - paragraphs have to be separated by blank lines.

Changed TSnippetsEditorDlg.BuildExtraActiveText method to no longer pre-process REML code string to compress spaces. No longer needed now that tagged text lexer processes spaces correctly itself.

Changed Dependencies dialogue box to display both a snippet's dependencies (as before) and the snippets it depends upon (new). Each is displayed in its own tab, and tabs that are displayed can be customised.
Modified calling code because of changes to signature of Execute methods.

Increased size of snippet kind, name and category controls.

Added new "units" snippet type.

Fixed problem where page control tab sets sometimes do not receive keyboard focus when clicked. This was a problem noted in compilers dialog box. Others using page control had same fix applied as a precaution.

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

* Reverted check list items to default behaviour. Clicking on item no longer toggles check mark. The modified behaviour was proving more problematic than helpful.
* Removed unit that had provided new behaviour.
* Adjusted other code as required.
