Add attempt to fix app nap, bump version, add project readme
First pass at allowing strip height to be modified, likely needs work.
Rename all instances of 'animation' as 'pattern'. This is PatternPaint, after all.
Remove some TODOs, make window height adjustable
Change look of image grid, comment updates
Allow the pattern editor to be dynamically resized
Bugfix: Don't clear the image when resizing the window!
