- Gui rewrite.

- Gui: Bug fixes and cleanup.
- Gui: Performance improvement (loading, resizing...etc)
- Added a simple PKG Viewer(Settings-> Utils -> PKG Viewer), added pkg folders will be saved.
- PKG Viewer: Shows game info(name, id, region...etc)
- PKG Viewer: Right click -> Install PKG to install/extract a game. Patch installation is also possible.
- Added option to dump game list  (Settings -> Utils -> Dump Game List), will be dumped to emu folder GameList.txt
