added fermilat query tool
added DelayedQuery component of FermiLAT (should inherit from API
eventually...)
updated .travis to install requests
added blank __init__ for importing
Add __init__.py and __all__ to fermilat package
Rename fermilat package to fermi

It's simpler and there are two detectors on Fermi:
LAT and GBM and eventually we want to access data from both.
Add missing self in FermiLAT_DelayedQuery
Add fermi package to the docs
Add a test for the Fermi query
Fix in FermiLAT_Query: use results._content, not results
Update Fermi unit test and docs with better example.
_content -> content
urllib -> requests (first refactor!)
refactor again to use class instances in the default import; discussion
may go on API prop page
