Fixed small error in SQL query - fixes #181
Minor updates to DB access code

Added some preliminary functionality to grade access, and made the
DB access classes not exit when errors occur with the JDBC driver or
the connection to the SQL server.
Account Fields now properly update upon newselect
Work on activity creation/management
User is now prompted before password is reset - fixes #203
Updated CreateAccount and AccountAccess

Blocked flag now works, exceptions thrown on delete
Merge branch 'master' of https://github.com/Donnervoegel/java
Settings button is now disabled when on Settings page

- This prevents the user from clicking "Settings" over and over,
  filling the page stack with the same page.
"Going Back" now easier

- Just call MasterFrame's goBack() method instead of the old, long call
  it used to be.
