Comment (by beebof):

 updated patch including changes from Paul H.

 Changes (most of them by Paul H. - thanks!):
 It determines the stream type and adds it only if it's teletext
 (reference: Changeset 8517).

 Resets the page cache when changing channel.

 Fix the drawing of the header only the last 32 characters are printable
 unlike
 other rows where 40 characters are printable.

 Only draw the header for pages that are in the current magazine and
 try to only update the page when necessary to try to reduce flicker.

 Add a status line above the header that shows available subpages
 or an error message like "Page Not Available".

 Make moving to the next/previous page and subpage a little smarter.

 Update SetBackgroundColor() to accept TTColor::TRANSPARENT used by
 the subtitle and news flash stuff.

 Update DrawLine() to use the 'start box' and 'end box' codes used by
 subtitle
 pages. Not quite working 100% right yet.

 Add support for the reveal function used by some teletext pages that hide
 the
 answers to a quiz until you press the reveal key.

 Add some defines for the page flags.

 Change a lot of tabs to spaces to make the source more in line with the
 rest of
 myth.

 A few fixes to the Fast Text stuff. (not working 100% yet)

 Other fixes I have forgot about.
