CodeSnip Old Code (SVN)

Removed unused unit references.

Added new TDatabase.Save method that saves database using new native file format.
Removed old Save method from IDatabaseEdit and _TDatabase.
Changed affected code to use TDatabase.Save instead of IDatabaseEdit.Save.

Moved field that records whether database has changed from _TDatabase into TDatabase and created a temporary TDatabase.__Updated property to provide access to the new field to the code that needs it in TDatabase.
Also removed IDatabaseEdit.Updated function and its implementation in TDatabase and added a TDatabase.IsDirty method to perform same role.
Modified TDatabase.Load to clear the dirty flag.
Changed affected code to use the new TDatabase method.

Added new GetReferrersTo and GetDependentsOf methods to TDatabase.
Removed IDatabaseEdit's GetReferrers and GetDependents and _IDatabase's GetReferrersTo and GetDependentsOf methods along with their implementations in _TDatabase.
Modified code that used removed _TDatabase methods to use the new TDatabase methods instead.

Removed unused unit references: FmAddCategoryDlg, FmDeleteCategoryDlg and FmRenameCategoryDlg.

Removed unused DB.UCategory unit reference.

Deleted redundant AddCategory, RenameACategory, DeleteACategory, CanRenameACategory and CanDeleteACategory public methods from TUserDBMgr, along with private CreateUserCatList method.

Added new method to remove a tag from a snippet.

Made TUserDBMgr.CanDuplicate and TUserDBMgr.CanEdit have same method bodies.

Renamed IDatabase and Database function, along with internal TDatabase class and PvtDatabase varibale by placing underscore in front of their names. This is to flag the items as "legacy" and to avoid name clashes with new database code being developed.
Modified all code that calls Database to use _Database instead.
