Typo/Bugs: Various small fixes...

mudlet::slot_connection_dlg_finnished() - finnished is a typo, only one 'n'.

TTextEdit::mCommandSeperator is a typo duplicating TTextEdit::mCommandSeparator.

toolTip for previous result on main console(s) was an unedited copy from
the one for next result.

TConsole::closeEvent(...) title for confirmation dialog was too long (dialog
is sized for the message text - title shortened and the message text
lengthened (and '?' added).

TBuffer.cpp: Revision to comment on ANSI CSI codes to correct a few details.

T2DMap::_getColor( int id) & T2DMap::getColor( int id ) Possible missing
initialisation to QColor variables.  Also missing "break" from "switch"
construct in latter.

(2 off) duplicate nested "if/else" constructs which makes one branch
unreachable for each inner "if".

T2DMapper.cpp Help message text reduced in size to fit smaller map windows,
also changed to yellow and placed at centre of bottom of map widget to
avoid previous clash with map information display at top of screen.

T2DMap::createLabel(...) generated dialogs now respect cancel option to
abort label creation.  The dialogs also gain a mudlet specific icon to
indicate their nature when task switching between applications (otherwise
an unspecific generic icon is used.)

T2DMap::slotmovePosition() generated dialog now respects cancel option to
abort movement.

T2DMap::slot_setCharacter() generated dialog now respects cancel option to
abort letter/symbol marker editing.  Message text lengthened to prevent
clipping of the dialog Title.  Validity of character now checked, with
space character now forcing clearing of the letter.  Further work to
permit the use of any UTF-8 character as a marker should be considered.

T2DMap::slot_deleteRoom() now deletes from end of list of rooms,
preventing possible race condition where roomIDs that have already
been deleted may be iterated over by mpMap->mpRoomDB->removeRoom().

T2DMap::slot_setRoomWeight() Message text lengthened and title shortened
to prevent clipping of the dialog Title.
