Auto-populate student id number in new learningexperiecne
Removed user-specific visual studio preferences
Removed orphan projects from solution
Semester column is now combobox column

Right now it doesn't show current value, however.
Changed semester and Service learning to combobox

Fixed previous issue, now problem is database is dirty
"Discipline-Based" != "Discipline Based" and so doesn't show up in
combobox
Changed combobox string definitions

Discipline-based -> Discipline-Based
Problem-based -> Problem-Based
This will keep the database clean, but dirty data isn't easily shown to
the user (combobox will show blank)
Added comments to document changes
Removed files which shouldn't be in repository
Further purged user-specific files from repo
Merge pull request #4 from mandella/master
