Replaces greater than operator ('>') with 'NOT BETWEEN 0 AND #'

Replaces equals operator ('=') with 'BETWEEN # AND #'

Tested against:

* Microsoft SQL Server 2005

* MySQL 4, 5.0 and 5.5

* Oracle 10g

* PostgreSQL 8.3, 8.4, 9.0

Notes:

* Useful to bypass weak and bespoke web application firewalls that

filter the greater than character

* The BETWEEN clause is SQL standard. Hence, this tamper script

should work against all (?) databases

>>> tamper('1 AND A > B--')

'1 AND A NOT BETWEEN 0 AND B--'

>>> tamper('1 AND A = B--')

'1 AND A BETWEEN B AND B--'
