Fix #22: Try to find data files if wrong case for non-Windows platforms

CI builds, but suggests formatting changes: https://travis-ci.org/OpenRCT2/OpenLoco/builds/332570277. Code LGTM, but haven't tested it. That might need hooking in some places for #14?

[IntelOrca]

How do I auto format? Is there a script I can run?

This should allow #14 to remove the case change to one of the paths. What do you mean by hooking? There is no interop here except the initial hook to get_file_path.

clang-format -i -style=file <path/to/file.cpp>

Tested this on top of #12, which works. Renamed a few DAT files, including my g1.DAT to use different casing. ~~~Unfortunately, this does lead to them no longer being found, so this patch doesn't seem to have the intended effect.~~~

This happened because validate_loco_install_path was not using the routine. I've added a quick patch.

Given @AaronVanGeffen already tested it, the code looks good.
