Release 0.0.6

Version 0.0.6 adds a few new features and a few bugfixes.

This version adds pausing/resuming and stopping to the paint operation. At any time during painting, press F4 to pause, and F4 again to resume. Press Esc to stop the paint operation entirely. A new paint operation can be started when the current one finishes or is stopped with Esc.

This version also fixes an OverflowError and memory error involving the grid alignment check feature. The OverflowError was being thrown due to proper intersection checks not occurring, and the memory error was not actually a memory error, but due to improper cloning/cropping of the game screenshot.
