- use fill_parent since we are still supporting api level 7.
- on the TrackListActivity, hide the empty view content
until the check unit dialog has been showned.
- fix the ChartView height. ChartView is no longer displayed
on the full canvas. The new design has a tab bar and a
zoom control.
- In TrackDetailActivity, only call methods of a tab fragment
if it is the current tab.
- for TrackEdit and MarkerEdit, use windowSoftInputMode=stateHidden
- improve layout for the map in MapFragment.
- fix text size for API level < 14.
- fix bug when inserting a statistics marker with a modified name
