Update to v094r18 release.

byuu says:

Okay yeah, lots of SNES coprocessor games were horribly broken. They
should be fixed now with the below changes:

Old syntax:

    auto programROM = root["rom[0]/name"].text();
    auto dataROM = root["rom[1]/name"].text();
    load_memory(root["ram[0]"]);

New syntax:

    auto rom = root.find("rom");
    auto ram = root.find("ram");
    auto programROM = rom(0)["name"].text();
    auto dataROM = rom(1)["name"].text();
    load_memory(ram(0));

Since I'm now relying on the XShm driver, which is multi-threaded, I'm
now compiling higan with -fopenmp. On FreeBSD, this requires linking
with -Wl,-rpath=/usr/local/lib -Wl,-rpath=/usr/local/lib/gcc49 to get
the right version of GOMP.

This gives a pretty nice speed boost for XShm, I go from around 101fps
to 111fps at 4x scale on the accuracy profile. The combination of
inlining the accuracy-PPU and parallelizing the XShm renderer about
evenly compensates now for the ~20% CPU overclock I gave up a while ago.

The WIP also has some other niceties from the newer version of nall.
Most noticeably, cheat code database searching is now instantaneous. No
more 3-second stall.
