Finished view achieved exercise goals

Currently has a bug where if a user has an achieved goal, but no
unachieved goal for that exercise, it won't let him add a new goal
Merge branch 'master' of github.com:Lynart/Project-LimitBreaker into issue116
Fixed allowing a user to add 0 into the goalfields
fixed not being able to add a new goal when there is an achieved goal for the exercise
put view into an update panel
Merge pull request #179 from andeic/issue116
