PPCCache: Make PLRU lookup tables static
Fix uninitialized GPU determinism mode for NAND titles or whatever.

m_strGPUDeterminismMode can be set by either the global or game
settings.  Either way, it's then supposed to be parsed into an enum,
m_GPUDeterminismMode.  However, the code to do this was placed right
after checking for game settings, which doesn't happen at all if there
isn't a valid title ID.  Move it outside the if block.

Dolphin[Qt|WX]: Miscellaneous cleanup.

DolphinQt:
 * Make the connect() calls explicit, not automatic
 * Follow better naming convention for the QActions
 * Remove the Open action from the toolbar.
Dolphin[Qt|WX]:
 * Move the "Skip Bundle" option to the root CMakeLists so that both DolphinQt and DolphinWX can use it.
