Go about installing Redis on Travis
I felt bad adding whitespace to this perfectly formatted README
What? Danger?
Let's just run this on latest. Don't need four builds going.
Redis install only needs to be run once
Load Redis extension before running PHP
Need to use `phpenv rehash` to reload PHP
As it turns out, I think we only need to include the Redis extension. Everything else is good to go.

Let's leave around the install-redis script just for funsies.
Make sure `redis-server` is started on boot
Tabs using spaces
Port over core's object cache test coverage, which gives us a nice set of tests out of the box
Core's behavior is to fail on `incr()` and `decr()` if the key doesn't exist.
Core expects `decr()` to never return a result less than 0
Test a subset of the object because we'll have two different Redis sockets going
Merge pull request #2 from alleyinteractive/basic-tests

Unit tests for the object cache
