Replaces all occurrences of operator equal ('=') with 'LIKE' counterpart
Tested against:
* Microsoft SQL Server 2005
* MySQL 4, 5.0 and 5.5
Notes:
* Useful to bypass weak and bespoke web application firewalls that
filter the equal character ('=')
* The LIKE operator is SQL standard. Hence, this tamper script
should work against all (?) databases
>>> tamper('SELECT * FROM users WHERE id=1')
'SELECT * FROM users WHERE id LIKE 1'
