Title: add usage to handle help for core and plugin commands

Addresses #39, #49 and #204.

* help for plugins now works!
* Remaining core commands to shocco: init, prefix, rehash, shims, version* . I've left alone since I'm not familiar enough with them.
* I've added a --short flag for later bad argument usage. Left alone bad argument handling since I don't know where and how to handle invalid options.
