#21 Remove global variable dependancy

[Craig Vincent]

It has been decided that we should do away with using
global variables and track vars altogether in an effort to
make the project more secure. This means all form
submission data will now be required to use the new
superglobals introduced in 4.1.0...this will make the
project require PHP 4.1.0 but the added security makes
it worthwhile.

Current pages need to be updated to reflect the new
policy change
