CFrame: Render to a child on Linux and Mac OS X.

This is needed to fix the hotkeys on those platforms.
DSP: Fixes behaviour for audio dmas of length 0

This behaviour was tested on a real (wii) console.
DSP: Do updates to DSP interrupt bits asap

This was being scheduled on the next possible event, which caused
timing issues (in FFCC, AI interrupt would fire before DSP interrupt)
Set the default radius to 100 for non-gcpad analog sticks.

The previous default of 70 was determined based on gc controllers, and is not right at all for the wii extensions.
DSP: Add minor delay to initial AIDMA interrupt

When AIDMA begins, the first thing it does is load the source address
and length into internal registers. It then triggers the AID interrupt.
Some begin the AIDMA process without all the data necessary for the
interrupt callback being set up already - they require a few more cycles
to set it up (the delay between the DMA being set to begin and the
interrupt firing). The value of this delay was approximated by tests on real
hardware.
Hide toolbar upon going fullscreen, rendering to main window.

DSP: DMA behaviour adjustments to fix regressions
Add TryParseVector to StringUtil.
Adds a nice way to have options be in a vector for results
Add the VideoCommon PostProcessing class.

This class loads all the common PP shader configuration options and passes those options through to a inherited class that OpenGL or D3D will have.
Makes it so all the common code for PP shaders is in VideoCommon instead of duplicating the code across each backend.
Add the PostProcessing class object to RenderBase in VideoCommon.
Backends will initialize this variable with their own inherited PostProcessing class object.
Change OpenGL's post processing to use the new VideoCommon PP object.

Let's OpenGL's PostProcessing namespace be changed to a class inheriting from VideoCommon's PostProcessing class.
Change all the post processing shaders to the new system.
Removes the README.txt file in favour of a new wiki page I'm going to generate.
Add the configuration dialog for post processing configuration options.
Only enables the config button when the shader options available to it
Merge pull request #693 from Sonicadvance1/PP-shaders-improvement

Improved system for post processing shaders.
Disable toolbar toggle in main window fullscreen
updated frametools
Merge pull request #793 from kamiyo/fixframetools

Update frametools.cpp to fix crashing when changing themes.
Placed ampersands and asterisks against type name
Merge pull request #735 from Armada651/d3dfullscreen_fixes

Fix hotkeys in Linux and Mac OS X (properly this time).
JIT: correctly set skipNext even if conditional-continue is off
