[snips-users] hostmon-osclient.freebsd memory parsing

[peiffer at engineer8 nts.umn.edu]

I have a box with a fairly large memory model.  I noted free memory
was always decoding to 0.  I noted a bit of run-on for digits between
avm and fre memory.  A patch is included below.  I put a limit to the 
numbers of digits that were to be included in avm and fre memory and
allowed for possibility that there may not be a space between them.
