Window controls & animations.

Here's a quick update for things I said I would fix.

• Added back and close window controls.
• Added some pretty animations.
• Fixed not being able to copy the destination and next system to your clipboard.
• Fixed the process not closing fully.

Intial beta release.

This is the initial release of Neutron (name to be changed). It's in a beta state, so development options are turned on (the developer console, etc). Please create an issue if something is, well, an issue.

This is Windows x64 only for now, but I will open it up to other platforms shortly.
