Godot: Godot_v3.0-beta1_mono_osx64 won't launch with Mono

[daniel-e-houghton]

Operating system or device, Godot version, GPU Model and driver (if graphics related):
Godot_v3.0-beta1_mono_osx64

Issue description:

I downloaded Godot_v3.0-beta1_mono_osx64 and Mono (for the first time) today. Godot wouldn't launch. I tried "Show Package Contents" and launched Godot in a terminal window to look at the error output and saw the message below. I noticed that Godot was looking for Mono.framework 5.4.0 and the version that I had downloaded today was 5.4.1. As an experiment I changed the name of my version folder to 5.4.0 and after doing that, Godot launched.

Mono: Initializing module...
The assembly mscorlib.dll was not found or could not be loaded.
It should have been installed in the `/Library/Frameworks/Mono.framework/Versions/5.4.0/lib/mono/4.5/mscorlib.dll' directory.

Rollback to Mono 5.4.0 or rebuild with 5.4.1.

Renaming folder will not work (mono use hardcoded paths?) but you can create symlink to current version (Godot starts but I didn't test Mono features):

sudo ln -s /Library/Frameworks/Mono.framework/Versions/Current /Library/Frameworks/Mono.framework/Versions/5.4.0

Thanks for the symlink idea!
