Added GuiMsgBoxOk and GuiMsgBoxYesNo, basic message boxes.
Added rating scraping to TheGamesDB scraper.
Added warning if platform ID is not set for a system the user has selected
to scrape.
Also add a "rating" and "timePlayed" variable to GameData. Some cleanup
in GameData and FolderData. Added sorting functions for rating and
timesPlayed to FolderData. Testing and UI support still tbd.
You should no longer see non-error output with ES except for "cleanly shutting down".
The new log file is located in ~/.emulationstation/es_log.txt.
If you notice any performance degredation, please tell me!
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 !$^&*()[]<>?;'"\.
