Changes to imagery

Added a background to the main tab.
Added a .ico to make it a bit more personalised.
Changed the size of the progress bar (moved also) *looking into tweaking it a bit more.
Moved 'check for updates' button.
Changed 'play' button, moved it. However, encountered a problem here where I couldn't keep the transparency of the button image and have it fit into the background and keep the functionality of the button itself. It still launches the client, but it acts more like a hyperlink than a button. Because of the flatstyle option;
Standard - adds a background to the button and ignores transparency in the image.
System - looks lame (for lack of a better term)
Popup - keeps image transparency but adds a border around the button, giving it the feel as though you have clicked a button. But the border itself ruins the aesthetic.
Flat - does almost exactly what I require but removes the feel as though you've clicked a button and may fill the user with a momentary feeling that nothing is happening.
So I may need a hand nutting out how to keep the style of the button (should we decide to keep it that way (if you like it)) yet make it act more like a button so when pressed it actually feels as though you pressed something.
So i'm looking, in essence, to alter the feedback given upon mouseclick or onclick.
