Began implementing GuiFastSelect. You can see what's currently in place by holding F2 and pressing up/down.
Hopefully fixed nearest neighbor filters with GuiImage.
If a theme.xml is not found in a system's directory, ES will now check for $HOME/.emulationstation/es_theme.xml. If present, it will load that.
Fixed GuiGameList image data not updating on system change/initial startup. (finally!)
Scrolling will now occur if the input is held (not just keyboards anymore!).
Initial XML gamelist support. If a file named gamelist.xml is present in the directory ES is run from, it will be parsed and the detailed GuiGameList will be used. Games are matched by absolute path, and a name, description, and image path can be read.
PugiXML is used for parsing XML files - its license can be found in src/pugiXML/pugiXML_license.txt.
SDL_image is used for loading screenshots with the detailed GuiGameList.
Almost all invalid bash characters should be escaped in ROM paths now - including !$^&*()[]<>?;'"\.
