Remove dependency on S3.  Combine Cache and Output paths into one.

* Need to point a webserver at the output folder and set the app config
variable: NON_S3_OUTPUT_URL.
* Cleaned up some error messages
* Some PEP8 issues
Add NetCDF deploy script for Debian based systems
Loosen requirements for now
Put some loose requirements in for paegan versions
Move most config to environmental variables.  Mucho simplier.

Keeps .env and .fab files for Dev and Production, respectivly
Match an additional standard_name when trying to get a valid variable.
Add the 'caching' flag to the Run model
Join the progress Thread
Log the model progress to a temp file and move it to the output location

That temp location is the defined CACHE_PATH, which I added back in.
In my defense, the tests ran locally.
Cleanup
Don't try to move a cache file if caching is turned off for the run
Add in paegan-transport requirement as a git commit
Merge pull request #18 from kwilcox/master

Allow local files to be used for input and export (no more S3 dependency).  Big fixes.
