Monthly snapshot 2.2.0-1 available

[Jeff Johnston]

It was requested that I add monthly snapshots for newlib to the ftp site so I am announcing
the first of said snapshots 2.2.0-1.  The snapshots will simply be a snapshot for the month and
will be -1, -2, -3, etc... until the next yearly snapshot which will be 2.3.0.  No changes are
made in the monthly snapshot regarding version, README, etc.. that are not already in the 
current repo.
