player.py requires mock, but it is not included with lib_deps

Issue Report

Description

The example in the docs fails if mock isn't installed on the user's system. This is fixed by installing mock. Mock is included with the test dependencies, but not lib_deps. I'd create a PR to simply add it to the installation dependencies, but I'm not sure if the intent is to require mock for all users.

Problem reproduction

sudo pip3 install omxplayer-wrapper
python3
>>> import omxplayer
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.5/dist-packages/omxplayer/__init__.py", line 1, in <module>
    from omxplayer.player import OMXPlayer
  File "/usr/local/lib/python3.5/dist-packages/omxplayer/player.py", line 10, in <module>
    from mock import Mock
ImportError: No module named 'mock'

Thanks for the report @superlou, You're quite right, this shouldn't be required. I'll remove this import and release a new version :+1:

OK, v0.3.2 is out, should fix this, let me know if not.

That fixed it, thanks!
