Added a module for unpacking OSZ archives.

Browse Source 
- Included 'zip4j' library to extract the ZIP archives. (Homepage: http://www.lingala.net/zip4j/)
- OSZ files are unpacked from the root directory by default, and the path can be changed in the configuration file.

Other changes:
- Fixed a critical issue in splash screen where thread would running before other states loaded. (blame: dea7e94)
