A quick little update to GopherMap. v0.2.0 greatly relaxes the validation of incoming lines, being a lot less fussy about missing tab characters and also about fully empty lines.

In the first take on this I was being pretty strict but, unsurprisingly, there are sites out there with likely-malformed maps that should otherwise work if you're chill about their mistakes.

I've got no desire for Rogallo to be harsh in this respect, so here's a much more relaxed version of GopherMap.

As of right now, the exceptions that are defined in the library are never raised. I've left them in for the moment because there's a window of time between this version being pushed to PyPI and Rogallo being updated (it does use the exceptions), where failure to supply them would cause Rogallo to crash under normal circumstances (nobody wants an unnecessary ImportError). Once I've updated Rogallo to pin a new lower bound, and removed use of the exceptions, I'll remove them from GopherMap.
