2. Added code to let the player skip past dialogue by leftclicking or hitting '.' 3. Removed the waitTicks() function and replaced all usage with delay() 4. Corrected various speed issues, the intro should run at the correct pace now 5. Talkie versions will no longer display the story screen during the intro, as in the original. 6. Moved the delay() function adjacent to other delay functions. svn-id: r20438
