Resolves #355

This PR changes the specs of the project. 80% line coverage is now required for all Phases with unit tests. 90% line coverage awards 1.25 points of extra credit. Here are the changes I made by phase:

Phase 3

• Coverage is collected on service package
• Videos are broken up into smaller pieces.
• Unit test section edited.
• Rubric edited.
• Getting started instructions includes directions for changing the code coverage runner to JaCoCo in IntelliJ, to match the output the autograder gives the students

Phase 4

• Coverage is collected on dataaccess.sql package
• Unit test section edited
• Rubric edited
• Video for unit test updated

Phase 5

• Coverage is collected on ServerFacade class
• Unit test section edited
• Rubric edtied
• Overview video updated

Note on Video updates

I recorded the videos through the BYU Online. I do not know if I should have asked them for transcripts. Each video has closed captions. I removed transcript links for all of Phase 3, and removed the links to just the videos changed for phases 4 and 5 (the word [transcript] is still there, following the pattern with the Server Facade video).
