Fixed a few things so this will work when they get it

Updated database usernames to use the current user by default so the students need not change it. Removed references to rerickso in populate-table.php in the process. Changed the height of tables.php section to 600 (this size should work great even on 768 height laptops some users might still have) Changed the name of the databse from USER_cs148_courses to USER_UVM_Courses as that is what the instructions say.

Only thing that the student would need to change is the pass.php file.
