Remove the largely superfluous query module so that all the code is in one file (otherwise if this is going to spread across multiple files it might as well become a package...)
Fix a couple logic bugs in the config handling (these were my fault)
Fix bug (that I introduced) with authentication; change user-agent string to say 'spacetelescope'
Reformatted readme so that long lines are wrapped
Slight update to the readme indicating that this is a fork of the original project
Add our license, keeping copy of original license intact as well.
