Add fast mode for testing (no animations)

[NathanLovato]

It takes about 3 minutes to run integration tests because the system is waiting for animations. We should look into skipping animations where possible to run things much faster. This is already in place for animated checks, but not for the rest. It would also make manual testing faster in development builds.

Godot's --time-scale 1000 command line argument may be worth considering here :slightly_smiling_face:

Didn't know about that one! Thanks much, it sounds great
