Working GPS-fix status indicator.

Also, lots of miscellaneous patching. Apparently WX was not enforcing the number of items in flexGridSizers at some point, so if you had a 3x2 sizer, and inserted 12 items into it, it would still work somehow. 

Anyways, they fixed the base issue, and now all the overfilled sizers fail all over the place, so they're updated to have the proper number of items now (or set to grow along the proper axis, when possible).

Updated Galil submodule with proper parsing of GPS lock status.

My text editor trims trailing whitespace on save, so that happened.
