Merge pull request #48 from Rdbaker/scholarship-content-approve

Added in 2 requested features to Scholarship module:

1) Any user can now submit Scholarship content to be approved by the Scholarship Chair. Upon approval, the content will be viewable by every user. The Scholarship Chair can still submit content themselves that will bypass the approval process.

2) When a user submits content, they will see a progress bar update based on the progress of the content upload. Previously, all that would happen was a loading icon on the cursor that showed the request being sent, leaving the user uninformed about the status of the upload.
