signwriter 6.x-2.0-beta2

* Added php version to info file to restrict to version 5 and up due to the use of features not available in php4.
- See #591800: Parse error: syntax error, unexpected '=', expecting ')' in /sites/all/modules/signwriter/signwriter.module on line 532
* SECURITY FIX - Fixed a security bug that allows arbitrary PHP code to be executed when using a signwriter
profile as an input filter, leading to a Cross Site Scripting vulnerability.
Any users with the ability to use input filters with signwriter profiles are able to exploit this vulnerability.
