Create course now populates instructor and TA names 

What i need to fix:

I added 2 methods; accessTAID and accessInstructorID. THese will grab the IDs of a specific string employee name you throw at it. What I want to do is that, when we pick a instructor or TA, the field for IDs will automatically populate. Im not sure if this is gonna be good, but so far Markus' accessTA and accessInstructors methods are broken. 
There seems to be a "int to NCHAR" error. Ive isolated that its a problem fetching the second part of the SQL which is the employee ID. There is a conversion error from the employee ID adding to the arraylist. If you can fix this you can change what I did.
