CodeSnip Old Code (SVN)

Modified validation of snippet's Description to included validation of active text as well as plain text.
Refactored active text validation code.
Moved some routines from public to private visibility.
A little renaming.
Some error messages changed.

Modified text search code that constructs the required search text for each snippet:
* Uses the active text plain text renderer to extract plain text from snippet's active text properties.
* Uses a string builder to construct the search text.

Prevented RTF and plain text active text renderers from clearing the builder object before each render. All renderers now act the same way.

Renamed TSnippet's Units, Depends and XRef properties to RequiredModules, RequiredSnippets and XRefs respectively and modified affected code accordingly.

Renamed all fields of TSnippetReferences record and made necessary changes to using code.

Chnaged methods that called Dataabase._Snippets.Find to use one of Database.Lookup, Database.TryLookup or Database.Contains methods.

Renamed IDatabase's Snippets property as _Snippets as a first step in elimination of the property.

Three new methods for looking up snippet IDs in database added to IDatabase and its implementation in TDatabase.

Changed IDatabaseEdit.UpdateSnippet from a function to a procedure (since revision 3907 return value was same as snippet passed as a parameter).
Modified calling code accordingly.

Simplified TDatabase.UpdateSnippet taking advantage of the fact that a snippet's ID can't change.
