Fix scripts in menu, re-add activity script, add new menu init script

Menu scripts weren't loading due to incorrect links.

Edit scripts and create new menu-specific script so that
- we don't call replace links on menu
- we track menu open even in GA object
- we change status bar color in menu and activities separately

Re-add the in-activity script, so that links open up in browser,
GA tracks correctly, and status bar is set up.
