Update to v094r40 release.

byuu says:

Changelog:
- updated to newest hiro API
- SFC performance profile builds once again
- hiro: Qt port completed

Errata 1: the hiro/Qt target won't run tomoko just yet. Starts by
crashing inside InputSettings because hiro/Qt isn't forcefully selecting
the first item added to a ComboButton just yet. Even with a monkey patch
to get around that, the UI is incredibly unstable. Lots of geometry
calculation bugs, and a crash when you try and access certain folders in
the browser dialog. Lots of work left to be done there, sadly.

Errata 2: the hiro/Windows port has black backgrounds on all ListView
items. It's because I need to test for unassigned colors and grab the
default Windows brush colors in those cases.

Note: alternating row colors on multi-column ListView widgets is gone
now. Not a bug. May add it back later, but I'm not sure. It doesn't
interact nicely with per-cell background colors.

Things left to do:

First, I have to fix the Windows and Qt target bugs.

Next, I need to go through and revise the hiro API even more (nothing
too major.)

Next, I need to update icarus to use the new hiro API, and add support
for the SFC games database.

Next, I have to rewrite my TSV->BML cheat code tool.

Next, I need to post a final WIP of higan+icarus publicly and wait a few
days.

Next, I need to fix any bugs reported from the final WIP that I can.

Finally, I should be able to release v095.
