Converted most of the regex definitions to use .format() syntax, for clarity.
Added some additional unit tests, primarily for testing dates like "nnn {units} ago", which are what I'm using the library to parse.
Reformatted many of the regexes for clarity. They now have consistent indentation.
All unit tests still pass, except for the `TestFrenchLocale.py` tests, which never worked on my computer (I have no locales installed at all - it's a server).
Whoops, missed a few regexes for conversion/reindentation.
Miscellaneous cleanup. Marked a whole bunch of strings as raw because they are. Lots of minor futzing to quiet PyLint.
Found some three-space indentation mixed with the four-space indentation, and cleared all that up.
Merge pull request #59 from fake-name/master

Reformatted all the Regexes, miscellanous neatifying.
