folder for uploaded csv files
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
uploading and deleting csv files now works
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
merge conflict in application layout solved
