few updates to layout

Profile tab :
1) scrollable and slightly reworked
2) added a progress bar(needs to be worked on)
-----------------
ExercisesActivity:
1) added an  accordion view template, there is a problem with it - the
screen becomes crammed with exercises which isn't good. may be solved by
using categories(tabs)?  any ideas ?
2) "Complete" button does nothing - working on returning results of an
activity..
