GPU: Add support for more framebuffer formats in display transfers.

Rasterize with the correct color component order.

- Fixes a regression with #594.

Clean up unaligned 32-bit memory reads

GPU: Fixed the RGBA8 input format and RGB8 output format

Pica/VertexShader: Fixed LOOP with more than one iteration.

in Display Transfers, tested with hwtests.

Previously it wouldn't jump back to the start of the loop code once it reached the end of the block.
Fixes the texture problems in a lot of games.

Common: Change names containing “Dolphin” or “PPSSPP” to something more generic

Sweeping cleanup of Common

Convert a few C stdlib asserts to Citra's own asserts

Rasterizer: Fixed a warning in GetWrappedTexCoord.

Redeclaring the variable inside the switch was causing weird behavior.

core/video_core: Use in-place construction where possible

More PICA200 Emulation Fixes

Not really sure where the difference is, but some applications seem to use this 1:1 the same way...

Pica/TextureEnvironment: Add support for the MAD-like texture combiners and clean up texture environment logic.

The change in depth range seems to reflect better to what applications are expecting, and makes for cleaner code overall (hence is more likely to reflect hardware behavior).
