security_scanner 6.x-1.0

Bugs resolved:
- Now works if there are more than one forms into the same page
- The thirth mode of the scanner was searching into the website after a form_alter that deletes every input different from text and textareas.
- If the thirth mode found more than one vulnerability that refer to the same form, it was added more times into the variable table.
New features:
- You can now add your own pattern and seed with it.
- The vulnerabilities output is now more clear.
Various:
- Checked xss_injector.module with coder
- Checked security_scanner.module with coder (only the developed part, the libraries part, that comes from drupal_web_test_case was not checked)
