fixed google scholar metadata retrieval

[silberzwiebel]

apparently, google scholar changed their layout which is why your scraper was confused by non-bibtex results. this lead to never-ending searches (from a user perspective) in docear. I've changed the links that are considered to be bibtex's and, more crucially, added a simple bibtex validator. the retrieval now works for me again. for the future, although I understand that there might be no future for docear, I highly suggest to add different services that don't break so easy:

1. https://bitbucket.org/bibsonomy/bibsonomy/wiki/documentation/api/Java%20API%20Examples
2. Possibly use https://github.com/ckreibich/scholar.py as a wrapper around an own scraper?
3. there might be other APIs out there, I didn't check

I didn't fully grasp the whole project layout in eclipse, so I also uploaded the resulting library file to github. Maybe you could write a blogpost about this?

Oh, well, I also tried to change the version number of the library (because it is a different version so the same version number is confusing) but then end-users would have to fiddle around in some other files instead of only exchanging the .jar file.
