Fixed bug where could not stop moving toolbar if on move mode when clicking 'share'.

Share still broken, made buttons instead of divs, made palettes prettier, renamed things to make more sense.

Fixing a bug.

Undo/redo working, code refactored.

Starting to implement imgur api. But going to refactor code a bit.

Share button now resizes and centres canvas, ready to convert to png.

Can toggle grid on and off.

Fixed movement bug.

Now pixels move when the grid is moved.

Moved more items into the window mousemove event rather than element mousemove events. Some minor cleanup.

Move on background.

Implementing UI elements: Can move palette around the screen. Part of code for moving point of view.

Fixed palette hovering bug.

Added eraser.

Function-ified some stuff.
