CodeSnip Old Code (SVN)

Deleted redundant TOverviewCategorisedTreeBuilder class.

Added new grouping of snippets by tag along with facility to render this grouping in the overview pane's tree-view.

Changed TGroup and TOverviewTreeBuilder to take a ISnippetIDList as constructor parameters instead of a TSnippetList.
Modified using code accordingly including replacing a call to IDatabase._Snippets with a call to IDatabase.SelectAll.

Recreated "parsnip" (v5 development) branch by branching trunk just after updating it with changes in v4.7.1.
