Create a tag for the live tracker

[pwalsh]

We are making changes to the tracker, and I want to keep an easily accessible version of the tracker as currently deployed.

Please add a new git tag called "2015" to https://github.com/okfn/open-budget-survey-tracker based on the last commit before you started working on the codebase.
