CodeSnip Old Code (SVN)

Added indicator of column and row containing caret in source code edit memo.

Modified snippets editor:
* Added support for Ctrl+X (cut), Ctrl+C (copy), Ctrl+V (paste), Ctrl+A (select all) and Ctrl+Z (undo) keyboard short cuts to all edit / memo controls using standard actions.
* Replaced default popup menus of edit controls with custom versions attached to above actions.

* Replaced code that checks validity of Extra active text with a call to TSnippetValidator.ValidateExtra.
* Moved assertions that ensure that all combo boxes have default items selected.
* Simplified TUserDBEditDlg.UpdateReference: now determine valid dependency snippet kinds with a call to TSnippetValidator.ValidDependsKinds rather than hard wiring the details.
* Modified TUserDBEditDlg.ValidateData to use renamed TSnippetValidator.ValidateDependsList method.

* Changed TUserDBEditDlg.InitControls to use TReservedCategories class to get name of user defined snippets category instead of using 'user' string literal.
* Increased width of snippet name edit box and categories list combo box.

Compile Results tab of snippets editor revised:
* "Select a Compiler" and "Selected Compiler Result" list boxes have been replaced by a single list box. This not only displays the compile result for each compiler but also provides a button for each one which enables the compile result to be selected from a drop down list.
* List box management code has been moved out into a separate UCompileResultsLBMgr unit.
* Removed TUserDBEditDlg.CLBRoutineRefsDrawItem method. Owner drawing of check list boxes now performed in TSnippetsChkListMgr.
* Image list containing LEDs was removed and replaced by a new custom, dynamically created, image list that knows how to map compile results onto the LEDs. As a result some buttons now have actions set in code to ensure they use the new custom image list.
* Brief help text applied to compile results pages.

Changed behaviour of check list boxes to toggle check state when any part of a list item is checked instead of requiring clicks on check boxes. Used new TChkListStateMgr to do this.

Disabled Render Extra Information button on Snippets Editor's Extra Information tab when no markup is entered in memo. Done by handling associated action's OnUpdate event.

Revised code that arranges controls within form to use static methods of TCtrlArranger from new UCtrlArranger unit.

Added facility to render and display REML code entered in the Extra Information tab of the snippets editor:
* New dialog box to displayed the rendered code as HTML.
* A button added to snippets editor to validate the entered code, compile it and then display it in the new dialog box.
* Change log removed from snippets editor unit (FmUserDBEdit).

Merged changes from /branches/os-fonts:22-106 branch.

These changes add support for default operating system fonts to main display and dialog boxes.
