Oekaki is updated.

New features:
1. White background by default for drawings for easier senbura viewing.
2. New color chooser.
3. Keybinds for undo, redo, bucket, pen, line, et cetera.

As always, you must use a modern browser to use Oekaki, like Mozilla Firefox, Google Chrome or IE 10-11.

Please enjoy new oekaki version (´･ω･`)
