Tool Panel Alterations

Some minor alterations have been done to the tool panel.  The following items have been re-designed to give a better effect of a sketched look : redo button, undo button and the paint tin tool.
The previous undo and redo buttons I had designed didn't give the desired look of the sketch effect, slightly drawn too neatly so I re-produced these:

The paint tin looked too neat also and when I looked back over the previous designs I had create I ended up working on the original one I'd done and worked on that producing a tool that looked well with the other tools portraying the desired effect I was looking for.
