wrote mc.ping
adjusted mc.ping to accept args

parses int on integer ping data
added mc.status

returns procfs data for the underlying java process
ping and memory added to self.property
removed mc.status

folded into mc.property since status was so single-purpose. This also
reduces the number of server_pids_up calls.
refactored ping to autopopulate connection args
corrected mc.ping test

all mc tests successfully run
mc.ping test fixed

fixed broken assumption (test) that the minecraft server truncated the
max-players value.

encoding changed to UCS2-LE, but Byte order swapped to be BE.
