* Rationalised use of TStringStream with relation to the required encoding when Unicode enabled.
* Replaced calls to TStringStreamEx with calls to TStringStream with TEncoding.Unicode passed to constructor.
* Removed TStringStreamEx from UUnicodeHelper and re-organised code somewhat.

Re-implemented THTMLTemplate.Create to load template from non-Unicode resources in a way that works on both Unicode and Ansi Delphis.

Merged trunk changes r401:429 into the delphi2010-port branch.

Development branch to make project compatible with Delphi 2010.
