credible and notCredible has different formats

[vlidholt]

The credible and notCredible lists have different formats, which makes parsing harder. I would propose merging the lists into one (the type tag could be 'reliable' for what's in the credible list) and or at least use the same format for both lists.

I just forked a version which didn't combine the files with the type tags, but did make the format of the credible list standard with the notCredible, along with minor fixes

Pull request #24 is also in, to implement those fixes.
