CodeSnip Old Code (SVN)

* Added new TSnippetValidator.ValidateExtra method to validate extra active text - checks for invalid hrefs in hyperlinks.
* Revised TSnippetValidator.Validate to call ValidateExtra.
* Reimplemented and shortened TSnippetValidator's HasValidDependsList overloaded methods, removing duplicated code. Renamed the methods as ValidateDependsList for consistency with other methods.
* Added new TSnippetValidator.ValidDependsKinds method that returns a set of snippet kinds that may be included in the dependency list of a specified snippet kind.

* 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.

Changed TCodeImporter.Execute to get name of imports category from TReservedCategories class instead of internally defined constant.

Changed TUserSnippetsLoader.LoadCategories to use TReservedCategories class to iterate through the reserved categories.

Changed TUserDBMgr.CreateUserCatList to use new TReservedCategories class to check if a category is reserved.

Added new UReservedCategories unit that implements a static class that provides information about reserved user defined categories.

Added new TCategoryInfo record that fully describes a category. Has Assign and Init methods.

* Renamed TUserDBMgr's Add, Edit and Delete methods to AddSnippet, EditSnippet and DeleteSnippet respectively to avoid confusion with similar methods that act on categories.
* Updated FmMain to use the renamed methods.

Changed TExceptionHandler.Handler to treat EFileStreamError exceptions as "expected" rather than "bug" exceptions. This fixes a bug in the database backup code (and other code the creates a file via a file stream) that was reporting a bug when a file was locked for writing.

Added paragraph that notes that users can defined their own categories.
