Release without phoenix_timex dependency

[IdahoEv]

Issue #40 eliminated the dependency on phoenix_timex by bumping timex support to 3.0.

The most recent release of coherence (3.1) still has the phoenix_timex dependency in it though. I can install master from git but a release would be lovely. :-)

I'm working on a rather big feature that i wanted to get done before releasing a new version. Let me think about an interim release.

I'm having a problem related to this also. I can't use timex 3.0

@AdrianRibao I found the following in my mix.exs is a good temporary workaround:

{:coherence, git: "git://github.com/smpallen99/coherence.git"},

@smpallen99 Any update on this release? Anything that we can help with?
