Updates install procedures

Version 0.1.5

Make it work with the latest versions of ObsPy, flake8, and matplotlib.

Version 0.1.4

Sep 30th 2015

* Minor change to adapt tests to the latest ObsPy version.
* Dropped official support for Python 2.6. It still works with
  it for now but I don't plan on further supporting it.

0.1.3

* Rejecting windows with very early start or very late end times. Greatly
  speeds up the algorithm.
* New config parameter ``max_time_before_first_arrival``.
* New optional time normalized energy signal to noise ratio. More resilient to
  random wiggles before the first arrival.
* New config parameter ``window_signal_to_noise_type``.

Pyflex 0.1.2

* Support for (de)serializing windows to and from JSON.
* Much faster STA/LTA computation.

Minor new version.

Initial release of Pyflex.

Already fairly stable.
