Convert SpigotMC module to use regexes for parsing. (#5507)
This makes the parsing a bit more robust at the cost of some
performance.
Additionally, this relaxes the parsing logic surrounding the handling of
the user counts to just grab the first integer after the timestamp and
treat it as the count of users.
Fixes: #4131
