Collectd-transmission

This release is practically the same as 2.3, but it had it's version number bumped to 3.0 to reflect the fact the project is migrating to Semantic Versioning

Major highlights:
- 100% code coverage
- supporting officially python 3.3, python 3.4
- readthedocs.org integration

- Fix bug 1
- Other minor issues

Added:
- tests
- code coverage reports
- documentation in ReST format build via sphinx

Extension is otherwise fully compatible with version 2.0

Rewrite to the metric definition system. As a result, this is a BREAKING change and upgrade from 1.3 requires some manual intervention. We bumped the major version to reflect this.

This release supports current as well as cumulative statistics as returned by transmission, a more PyPi integrated documentation and various small fixes

To upgrade you can run scripts/upgrade_from_1_3_to_2_0. It will create RRDs with the requested new names via hardlinks. Feel free to remove the old ones after you are done migrating whatever you might be migrating.

- Move to a more flexible metric definition scheme
- Minor breaking change: secondsActive is now a gauge, not a counter. That was also done in 1.1 but had to be reverted in 1.2
