Transparent Background and Saturation
Transformations and Icons Added
Fixed transparency bug
Updated Icons
Color Options and Grid Bug Fix

There are now more options for colors: when you click on the left or
right color, a color chooser pops up that gives more color options
including transparency. There was a bug where the grid was only drawn
for the primary image in tiled mode, but it has been fixed.
Added Redo Button and Text Tool
Gradient Tool Added

Currently, three gradients are supported: linear, mirrored, and radial.
I hope in the future for JEIE to support conical and square gradients. I
found a ConicalGradientPaint class online, but I can't find licensing
information. It can be found here:

ImageAction is an interface again.
Removed incorrect notice from file.
Fixed cache copying bug.
Added copyright notices.
