v0.5.2
--------
* FIXED: Installation requirements are more loose now. Pure Python packages are installed on the go with pip. Non-pure required Python packages stop installation and tell you what to install manually. Non-pure recommended Python packages allow you to install psychopy_ext but give a warning about what's missing.
* FIXED: In older PsychoPy versions, BaseVisualStim is _BaseVisualStim, so now accepting both.

--------
* FIXED: mouse inherited from Exp to Task
* DEMOS: updated post_trial syntax
