CodeSnip Old Code (SVN)

Modified TCodeImporter to read data into an editable snippet instead of editable snippet data.

NOTE: there are some problems that will required implementation of linked spaces / synch spaces to solve.

Modified comments and string literals referring to the "user" database or "user-defined snippets" to remove or qualify the word "user".

Overhauled TUserInfo record:
+ Removed Assign method (not needed: direct assignment works just fine)
+ Removed Init method: can use CreateNull method in its place
+ Corrected spelling of "null" in method names.
+ Made Details and Comments fields into read-only properties and so made record immutable.
Updated using code re changes.

Overhauled TUserDetails record:
+ Removed Assign method (not needed: direct assignment works just fine)
+ Removed Init method: can use CreateNull method in its place
+ Corrected spelling of "null" in method names.
+ Made Name and Email properties read only and so made record immutable.
Updated using code re changes.

Removed temporary Category (ID) property from TSnippetBase and all code that supported using the property.
Updated affected code by removing all references to category IDs.

Removed redundant TSnippetInfo method.

Removed reference to TReservedCategories by hard wiring the special import category ID as a string literal.

Note: this is a temporary change en-route to removing support for categories.

Added new IStringList.IsEmpty method and its implementation in TIStringList.
Modified all code that tested IStringList.Count against zero to use IStringList.IsEmpty intead.

Modified TCodeImporter to ensure snippet's title is non-empty: uses snippet ID if no title present for a snippet.

Replaced TSnippet's Language function with LanguageID property that uses the pre-existing implementation in TDBSnippet. Modified using code accordingly.
Deleted TSnippet.HighlightSource property. Modified using code to deduce if source code highlighting required by examining the LanguageID property.
