Added overhauled preliminary schema for what frontend wants.
Completed the schema based on the "Graduate application requirements"
document from the frontend
Renamed Admission Schema for conventions-sake
Added two requested Booleans

Stu_Front-end requested Boolean for if the app has been started or if it
needs to be created. (They actually requested int where 0=non-exist,
1=exists, 2=complete, but that could get lost-in-translation or out of
hand)
Updated schema to match front-end fixes
Added preliminary tests for Application schema
Merge branch 'unstable'
