PKG Loader rewritten
* Rewritten unpkg.c -> Loader/PKG.cpp * MainFrame::InstallPkg now *only* installs the PKG. * Fixed crash when unpacking big debug PKG files. * Debug PKGs are no longer recrypted. * 'About...' dialog updated to remove PKG-related notice. * Unpkg removed. NOTE: The class PKGLoader is using wxWidgets functions to access the files. I think VFS would be better, but the Emulator isn't necessarily running when installing the PKG. In the other hand, initializing VFS with RPCS3 may be somewhat risky... Any alternatives? TODO: Get rid of the decrypted "*.dec" files, and try to decrypt and read contents of the PKG on the fly using the information stored in m_entries.
