Strip path components when looking for themes

[dpaleino]

Fix #49.

Fix search for parent themes by stripping leading path components, which may result in false negatives.

Thanks! I’ll get a new release out shortly. (Mind you, Coil isn’t much maintained these days, so you may expect breakage like this.)

Well, I'm having another error, this time with jinja... is there any better option than coil for non-tech users to use nikola? :)

[Kwpolska]

I’m afraid there isn’t any. Coil was not updated for quite a few months, it does not reflect changes made in recent Nikola versions. You would probably be better off using the command-line, or if that’s not feasible, I’m afraid you’ll need some other CMS… Sorry for that.

(Coil needs new maintainers, the codebase is one big hack though)
