Title related activities

Similar activities should have the same title to align with the naming convention of Strava (Most users moved to it).

Eg.
Cycling, Mountain Biking, Road Cycling, etc. supposed to be "Ride"
Running, Jogging, etc. supposed to be "Run"

Basically, this part needs to be improved: https://github.com/glennreyes/runtastic-gpx/blob/master/index.js#L166-L170
