#1 Use images for emulator selection

[jlocke]

Currently, the text-only emulator list across the top of the screen makes the overall experience seem somewhat boring. Further, the names are populated solely by what the user enters in the gfuel.conf file and there's no flexibility.

Now that a scrollbar has been created for the emulator list, there are only three elements displayed there at any given moment. This opens up possibilities of displaying much larger, more interesting images (icons, logos, or other) to make the screen look less boring.

The current idea is to create another configuration file that simply contains mappings between system names (entered in gfuel.conf) and images (kept in some new directoy). A mapping might look like:

NES nes.png

where NES is the name listed in gfuel.conf, and nes.png is the image to use for this system. When gfuel is launched, the QLabel will be populated with this picture instead of text. If no picture is found in this mapping file, text will be displayed as normal so we don't cause breakage.
