PHPIDS integration rewrite Sprint tasks

The following tasks are planned to be tackled on the PHPIDS integration Sprint-day.
(List incomplete)

Let's concentrate all power on a Drupal 7 version and backport to Drupal 6 as good as possible; totally drop Drupal 5 support.

• Decide what features PHPIDS integration should have
• Decide it's architecture
• How reports should look like (what information is interesting for users and how to display it?)
• #1706446: Library path to sites/all/libraries
  Introduce the usage of libraries
• Integrate with rules 2.x
• Introduce "bypass" permission?
• #1367076: Support of phpids 0.7
  Make sure current PHPIDS version 0.7 is fully supported.
• Use temporary:// for phpids temporary files
• Think about using class auto-loading for PHPIDS files
• Make installation as easy as possible
• Get rid of the warning.html thing, and manual additions in robots.txt

Clean up code for best practices and coding standards.

• Don't set variables on installation
• Don't mix with code of former drupal versions
• There's no hook_perm() in drupal 7
• Don't use camelCase naming for global static functions
• Put less logic into hook_init().
