CodeSnip Old Code (SVN)

* Added new EValidation exception class that optionally records a selection specifying location of an error where this makes sense.
* Modified EDataEntry exception to descends from EValidation: new constructors added to take selections.

Added new TSelection record that encapsulates a selection defined by its start position and length.

Removed unused EREMLEntities exception class.

Corrected comment that said validator raises exception when it does not.

Some methods were raising an ECodeSnip derived exception when programming faults were detected. These were replaced by assertions.

Partially implemented suggestion in comment to feature request 3105288 so that errors reported when clicking "Render Extra Information" button on Snippets Editor's Extra Information tab now refocuses memo control containing error.

* Created new UMemoCaretPosDisplayMgr unit to take care of displaying caret position of memo controls in associated labels.
* Revised snippets editor to use new TMemoCaretPosDisplayMgr to display memo caret positions and added caret position display for extra information memo.

Updated copyright date ranges to include 2010.

Removed URLDecode and URLEncode functions from UHTMLUtils unit. Replaced all calls to these functions with calls to URIDecode and URIEncode from the UURIEncode unit.

* Added new DB.USnippetKindGroup unit that provides a skeleton implementation of a snippet kind group in the database along with supporting types.
* Added DUnit test suite for DB.USnippetKindGroup unit.
