support new activities

[borivojevic]

• the activity names have changed and activities have an optional group field in both summaries and storylines
  • the API v1 activities can be mapped to an activity group (which also includes stationary/indoor walking, cycling and running variants) or exact activity name in API 1.1 as follows:
  • activity: wlk -> group: walking or activity: walking
  • activity: cyc -> group: cycling or activity: cycling
  • activity: run -> group: running or activity: running
  • activity: trp -> group: transport
• new activities have been added and there is now an API endpoint for querying currently supported activities, see Activity list API. For human readable version, see table of activities
  note that currently Moves for Android only supports activities walking, cycling, running and transport
