Fixing requires so they work on my Windows copy (and simplifying the require tree)

Move SQL and database scripts to sql/.

Introducing upgrade scripts.

Moving structure-like data to the init.sql script:
* TermSemesters: the possible semester seasons of a year (spring, fall, ...)
* PositionTypes: the possible position types (lecture, lab, wsl, grader)
* EventTypes: the internally-used EventType data

Placing final(ish) initial data for a new install in init.sql:
* Initial Configurations:
  - logDebug = false
  - adminCreated = false
  - emailDomain = 'csug.rochester.edu'
  - emailLinkBase = 'http://www.csug.rochester.edu/TARS/'
  - enableLogin = true
  - currentTerm = null
* Initial Users:
  - root: emailVerified=true, canReset=true, pass=null
  - tarsbug@csug.rochester.edu: emailVerified=true, canReset=false, pass=null
* Initial ResetTokens:
  - A single reset token for user "root" allowing an admin to set a root password.
Disabled account support and the ability for users to reset password without email verification.

Now "root" account can function correctly.

The "tarsbug@csug.rochester.edu" account is a disabled account.
Token encoding to URL-safe strings was very broken. Replaced temporarily with code that directly base64_encodes the strval(number).
Fixed phone numbers with leading zeros being displayed improperly.
Minor fix to appearance of set password form.

Always go to "/" instead of "/index.php"
Use local jquery (to be added when I get Internet access)
Remove old unused files
Version 0.9.0: Update Session code & new Setup page

Fixes possible double session_start() call on index.php before redirect

Session code now centralizes session_start() calls better.
Change "ERROR_FORM_FIELD" to "ERROR_ACTION" and made it include all the other "external" error types.
Implementing Bug Reporting form
index.js for bug reporting
Add jQuery to project folder
Aciton function for Bug Report support. All emails should encode HTML entities (XSS).
