Fix creds parsing on files that have had their line endings changed to CRLFs.

[aricart]

FIX #71 - Relaxed regex to allow optional carriage returns. Target content also had to change from .+, to more specifically grab the non-whitespace content.

Note that this regex is fairly complicated, an alternative fix simply strips carriage returns from the input before parsing. I am OK with doing that change instead, as this required quite a bit of staring (with Matthias).

LGTM - Be good to see more test cases with users adding different comments etc. Essentially as long as jwt and pk are valid we should be good.
