Creating common subproject for common stuff.

Right now this is for Statsd serialization which shouldn't change between versions of Metrics. Have not converted metrics3 to use it yet.
Moving common code.
Remove .count string from the end of the base count values. Statsd clients usually expect this to indicate a counter value (which can aggregate with sum) instead of a gauge like value.
Moved the old metrics 2 reporter to use the standardized Statsd object instead of its own broken one.
Fixing whitespace.
Removed old Statsd serialization code.
Upping version to 4.0.0-SNAPSHOT
Versioning and giving a good name for the common code.
Renaming StatsdReporter to StatsDReporter for metrics2 to match naming convention for metrics3.
Fixing copyright notices
Updating documentation for better Metrics 2 info.
Fixing issue where metrics2 doesn't try to connect to statsd first.
Merge pull request #12 from mkeesey/readytalk-master

Centralize StatsD code, remove the appending of "count" to metric names, set versions to 4.0.0-SNAPSHOT for both libs
