Package relies on config.json to be present

[danielkhan]

The documentation suggests that the config file ist optional but you are trying to access it without checking for existence.

There is a valid lookup for less-watch-compiler.config.json afterwards - I didn't do a pull request because I don't know what's the plan with the other config file name.

Yeah, I was trying to run less-watch-compiler and it was crashing trying to look for the files.
