Env Load

For your consideration: this does two things,

1. removes the need to add all of the default cog-script to the path. Instead only cog is exposed and all the other defaults are called by their full path. This ensures cog doesn't pollute the global namespace.

2. (more fun) whenever cog is run it will automatically source a .env file, if it exists. That means you can run something like cog solr and you don't have to include all the variables inside the file, it'll pick them up out of the .env file. My thought is that we can then move cog-ssh over to the default and just expose a variable for it.

@mrpaulphan, thoughts on this? I'd like to clean up our cog implementation so we're using it consistently across projects.
