Updated the conf.d file globbing support to merge in a more sophisticated way
glob include conf parse fix
Added time interval support

New configuration parameter :interval. If :interval is set, stats are
sent every :interval seconds, else if :every is set, stats are sent
every :every row, else stats are sent once per second.
Added support for "unmetrics"

A really bad name for non-matching rows. Instead of throwing away non-
matching rows, the unmetrics feature let's the user count those as well
with the metrics names given by a list of "unmetrics".
Fix for nested captures

If we use nested captures, we can get a MatchData set where some
members are nil (meaning that that capture did not match anything).
Those should not be counted
Added *.gem to avoid checking in the gem files
Bumped the gemspec version
Merge remote-tracking branch 'origin/feature_intervals_and_unmetrics' to support Stefans new features
