Parsing errors in valid metadata

[mynameismon]

Kindle has a weird system of producing the metadata for clippings. Digging through my personal copy, I find there are two main formats that it follows, one that the parser allows for. The other format is:

- Your <type> at location <startloc>-<endloc>| Added on <day>, <date> <month> <year> <HH>:<MM>:<SS>

I have tried to fix this using this regex, and will try to open a PR by the end of this week to fix this. Do check the regex and try to break it.
