CodeSnip Old Code (SVN)

* 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.

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 button to "compile" tab of Snippets Editor to display unit used to test compile snippet.
* Set action for btnSetAllSuccess in designer and deleted code that explicitly set this action and action for btnSetAllQuery.

Renamed FmUserDBEditDlg form unit as FmSnippetsEditorDlg and renamed form class from TUserDBEditDlg to TSnippetsEditorDlg. Modified using UUserDBMgr unit accordingly.
