Issue fixes and deleted comments

+ Added  preselectOpenRoles to fix Issue #7
- Should fix Issue #6
- Comments can be read in the last commits. I deleted them now for less filesize.
Role checkboxes updated

Fix of open role checkboxes not showing their "checked" state.
It might be the best to simply call click() on them, since bootstrap does some stuff behind the scenes.
