Massive branding updates

I spent much of the day updating various text strings of branding issues, such as KDE -> TDE, K Desktop -> Trinity Desktop. These strings included What's This, Quick Help, KMessageBox, printf, i18n strings, etc. There was no easy search-and-replace method because many strings had to be read in context before deciding to change anything. Grunt work --- but I think most of this is now behind us. I still have the lsm files to update. Please let me know after rebuilding with the latest GIT sources when you notice remnant strings needing attention and let me know whether I got cross-eyed and changed something I should not have.
