important form-fix for actor new(that one with ajax) ->read more

I changed form_for with fields_for in the partial part, this way the whole new site only contains one form and the submitbutton is now moved from the partial into the new ( the 'main' view). If you plan to add more stuff in the same form, use --> fields_for(:some shit) do |fields|
started work on edit actor types.
very much work in progress
edit actor_types works. some serious refactoring needs doing with passing on information_types
Merge branch 'master' into edit_actor_types

wrote the filter. The actor create is not working sadly
extended application layout to insert headers per page

deleted unnecessary jquery import from apllications.js
custom javascripts can now be loaded ona per page basis wth:

<% content_for :header do %>
  <%= javascript_include_tag 'actor/test' %>
<% end %>

would link to /app/assets/javascript/actor/test.js
added a possibly working filter
Merge branch 'edit_actor_types'
iterating over params to add/change informations types in actor_type_controller

fixed the issue with the label that wasn't checking/unchecking the associated checkboxes. check_box tag helper is buggy. need to pull a little hack to set id's and names manually.
fixed translations to urs' super slick implementation

sorry for working on the master branch...
secured the post update aswell
