Jit64: disable non-IEEE mode emulation

I give up. Merging the ppc_fp branch has caused issues in numerous games
and I can't find the bug. I'm leaving this merged to enable easy
recompilation for people who would like to play games that benefit from
non-IEEE mode emulation (e.g. Starfox Assault).
Readme: Windows XP is not supported anymore.

Cf. issue 6785. The decision had been made weeks ago but no one thought of updating the readme.
wayland: Add bits required to run as a wayland client.
Modified project settings
Stop building GLExtensions.cpp twice(One in GL, one in software). We don't need to build it twice, this'll save a bit of time in the build process.
Also a bit of spacing cleanup.
Revert "Modified project settings"

This reverts commit 6ad4c0efa6f2c247ed3cdceb141b3c9f66b2a1e5.
