Fixed a regression introduced in ca3c3a7b56d7c82441e1071a658f3e0537a97d48 where looping over and deleting record-valued keyword cards could, in some cases, result in an exception depending on what order they were deleted in

Finally fully deprecated pyfits.new_table in favor of more explicit class methods.  Added support for an ascii=True argument to ColDefs for cases where ambiguity can't otherwise be resolved.  Also fixed up a few minor formatting issues in the documentation that I found while updating the docs to discuss the new table creation methods.

Fixes the DeprecationWarning reported in https://github.com/spacetelescope/PyFITS/issues/45 The code here for mucking with urllib is, as far as I can tell, just a workaround for http://bugs.python.org/issue1566800 and shouldn't apply to newer Python versions anyways
