CodeSnip Old Code (SVN)

Restricted valid tags to letters, numbers, underscore, hyphen or space. I've done this to allow special punctuation characters in a future search box to have a reserved meaning and not to be confused with part of a tag.
Also removed facility to "prepare" a tag: user must pass a valid tag to constructor.
Fixed a small bug in constructor's exception creation.

Added changes to revision 4019 to v5 change-log.

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.

Removed unused USnippetIDs unit from project.
Changed affected units to use CS.Database.Snippets instead.

Removed unused unit reference to USnippetIDs.

Copied TSnippetIDList class from USnippetIDs.

Temporarily renamed TSnippet as TNewSnippet: this is to avoid name clashes with existing TSnippet. Once the old implementation has been removed TNewSnippet can be changed back to TSnippet.

Added MPL 2.0 boilerplate to units recently copied from experimental branch.

Modified TSnippetBase, TSnippet and TPartialSnippet to compile in "parsnip", changing some property types and adjusting data type names as necessary. Also tweked some getter and setter code.
Commented out TDBSnippetIDList: it is not needed since we already have similar TSnippetIDList.

Changed TDBSnippetID type (as used in "experimental" branch) to the similar TSnippetID (as used in "parsnip").
