fix bug #17

now renames files in WCS folder
after applying astrometrical fit
added module for getting information from simbad

also refactored to move the coords module to redrovor
where it makes more sense than having it with the website
code
messed up on cherry-picking replacing with correct coords.py
update coords and simbad

merged changes from thirdpass upstream
Merge branch 'thirdpass'

Conflicts:
	redrovor/coords.py
	rovorweb/targets/fields.py
	rovorweb/targets/forms.py
	rovorweb/targets/models.py
fixed problem with merging forms.py
