Gets rid of properties defined as both MAKE_SEQ_PROPERTY/MAKE_MAP_PROPERTY, which are just a bad idea. Instead, adds a way for map properties to define a separate "keys" interface.

This will be a good way to make sure everything in the tests work under
a frozen environment.
NOTE: The application builds and runs, but no tests are collected. We
still need to figure out how we want to handle tests. Freeze them all
and modify test collection? Add py/test files to the build directory and
try to run them?
This is necessary because when Python is initialized, it takes the codec to use from GetConsoleCP() and GetConsoleOutputCP() without bothering to check whether the given codec is available. However, in most cases, the console codepage will be the same as the ANSI codepage (ie. GetACP()) which is always supported by Python via the 'mbcs' codec.
So what we do is we check whether the console codepage is frozen in, and if not, we set the console codepage to the ANSI codepage and set the stdin/stdout/stderr encoding to 'mbcs'.
This is still not a perfect solution because the ACP may not be able to encode all characters that the application is printing, which would still result in unexpected errors. Ideally, we'd pull in Python 3.6's _io._WindowsConsoleIO class, which bypasses this whole mess by directly using the wide-character Windows APIs to write to the console.
A notable change is that the color scale is now applied *before* texture blending, matching the FFP. If this breaks anything, we might want to add a configuration option for this.
This also implements the remaining combine modes, CM_dot3_rgb and CM_dot3_rgba, and fixes the broken CM_subtract mode (which currently worked the same way as CM_add).

Set "mirror" camera to always have the same roll as the mirror
-> otherwise the model in the mirror will move unexpectedly
Set y coordinate of the mirror corners to the cameras distance
-> This fixes a crash and keep the mirrored model at correct sizer
Closes: #194
