Added transient (for morphia) field for the ELO to avoid needing an
unnecessary additional object in the blobs.  This will not be stored in
the db and is mostly used when running elo data on a user.
Number running is updated to avoid repeating logic, broke in some new
lambdas for fun.  Unsure of reply type structure for getting the
history/stats.
Endpoint added for history, though the reply type is not yet nailed
down.
Calculations, they're pretty darn simple.
Ignoring mac index files
Standing removed, the system is fast enough to not need to persist the
current standings.  It may need to be re-added if performance is an
issue.
Removed remnants from the removed Standing pojo
History item used for returning game history snapshots.
Added HistoryBlob to the Season resource reply
Additional history handling added.  Added in a post operation, optional,
anon function.
Added copy ctor (and empty ctor)
removed standing class, it seems unnecessary
