Some fix-ups of textattr() in ANSI mode. #ifdef'ed out support for

ESC[22m and ESC[25m (Unfortunately not widely supported).
Fix old calculations to match new calculations so the equality test is
meaningfull (should result in less verbose messages).

Still no idea what is causing the bright attribute to be stuck high when
SyncTERM is ran as a door under Synchronet and accessed using mTel.
