Regular & electric bike

[Bahjesaispas]

Here in Paris we have now 2 types of velib. One is electric and the other one is a regular one.
On the OpenBikeSharing app we just have the number of bikes available at the station, we don't know the type of bike available.

It's actually supported on the CityBikes API (eskerda/pybikes#299) so we could support it as well in the app.
