- Reset the plugin-info to the values originally set by Mika
 excpetion the website: as first_child is not mentionend on
his website anymore.
- Dependency on "toad" is removed, as the project does not exist anymore on
  github
- the check for the current page is simplified and made to work with and without "mod_rewite"
- The workaround for Behavoir::loadPageHack is removed as the problem seams
  to be fixed with the latest commit of wolfcms
