make prefixes for all metrics configurable
Merge branch 'configurable-prefix' of https://github.com/Dieterbe/statsd into configurable-metric-namespace

Conflicts:
	backends/graphite.js
	exampleConfig.js
modify key namespacing to be easier to configure

This makes some changes to what the default key namespaces are and how they are
configured. Basically it puts the config under the graphite key and doesn't
need the user to take care of where dots are set.
fix the tests
Merge branch 'master' into configurable-metric-namespace

	backends/graphite.js
	exampleConfig.js
add a flag for namespacing backwards compatibility

This introduces the `graphite.legacyNamespace` boolean flag which can be used
to maintain backwards compatibility to how stats are sent to graphite.
update tests to reflect non-legacy namespace
add tests for graphite legacy namespace
add set type to configurable namespace
Merge branch 'master' into configurable-metric-namespace
Updated stats.js to delete counters

Counters are now deleted after being used, not set to zero.  This solves
some issues with high load on Graphite and certain graphing functions
which require null instead of 0 counters.
Merge branch 'null_counters' of https://github.com/ReturnPath/statsd into nullcounters
Update stats.js

Changed from delete to undefined, per some info on delete from Mozilla https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Operators/delete

This keeps the array element there, just sets it's value to undefined.
Update test/graphite_tests.js

Updating the test to work with new null count change.
Adds Windows Service support

This assumes that there is a local 'config.js' within
the statsd folder.

Update stats.js

Added a config option delete_counters with a default: false to control the behavior of the counters metrics to delete.
making the repeater backend ipv4 only again

some people reported problems with it, so we have to look into a better
configurable solution for this.
