so far only minor changes to fermi
more work on FERMI LAT query tool

Conflicts:

	astroquery/fermi/core.py
fermi refactor - more progress
fermi queries still fail but at least the tests won't bug anyone any
more
fermi tests pass!  Still questionable whether they do anything...
added fermi data
add fermi setup
add other fermi data
add socket guard to fermi tests: they should be forced to fail if
non-remote tests try to access a remote site
FERMI tests now pass; monkeypatching these proved tricky because the
wrong data was being passed around before switching to
commons.send_request
