Activity items have different height sizes. 

#### Issue (only desktop and tablets, not phones):
  - Activityitems have dynamic content for its caption text. What sometimes causes bad alignment vertically between them.

#### Solution:
  - By default all the items have the same height size, except for mobile where the height will depend on its content. For desktop we add the functionallity hover state to show the text what has been cut-off by its max-size.

#### Changes:
  - Compass upped to 1.0.1.  Sass will be installed automatically by compass.
  - Without any intention a known bug was fixed. (Repeated activities are no longer shown).
