mocha now supports a user defined theme for output colors. In the process I ended up doing a lot of stuff related to the config. First thing I did was swap to fatih/color for colored output, since it handles stuff like colors in command prompt and removing color when output is piped.

Then I refactored the config module. Earlier I would pass around a MochaConfiguration object through every function. Now I use a config singleton that’s accessible from any function. Why? Because it means I don’t need to pass the object every time I want to log information. Also means I don’t need to pass mochaDir through almost every function in the codebase.

Getting user defined themes was a bit complicated because I needed a good way to handle a default theme so output doesn’t look bad if parsing fails. I handled this by only using the configured theme if every color resolves properly. Otherwise output falls back to the already loaded default theme. Due to this you still get colored output even if there are errors or warning before the configuration and theme is loaded.
