- Includes a check to confirm no hash collisions.

- Fixes uniform issue on AMD.

- Alpha testing is not done with float32 precision, this makes the HW renderer match the SW renderer.

citra-qt: save hardware-rendering and shaders-jit settings

citra-qt: Add icon to the OS X app

Loader: Implement NCCH encryption check

Before this changing these settings from the GUI would apply the
settings, but they were reseted to the default values when exiting
citra.

Previously the Mac app didn't have any icon.

Remove newlines in LOG_* calls

Fixed spelling errors

The LOG_* function itself already appends one.

citra-qt: high-DPI fixes and Retina on OS X

Properly hides the game list upon toggling from external
window mode to single window mode. Previously, both the game
list and the render window would have been shown at the same
time upon toggling.

The OS will render the widgets using the system screen DPI (instead of
being locked at @1x resolution).

This has no impact on the existing high-DPI rendering code in Citra,
which means that the resolution of the emulated content is increased
to the real number of pixels, as on other platforms.

Instead of letting CMake re-generate an automatic Info.plist file on
every build, use our own. This allows greater control on the application
bundle settings.

Prevents error verifying host key (and we can't manually verify since
the prompt is obviously non-interactive).
