Rebased against develop@95131ca23a6b28e295be839964f9663b0e07c559
ActiveScaffold removed from the environment_controller
actionlinks rewritten as action => :index + a query string

Note that I had to change the puppetclass index method to use Puppetclass.searchlogic() rather than Puppetclass.search(). It is not clear why.

I cant merge this as it uses the searchlogic, please remove the search bit and I'll commit it.

e.g. in puppetclass controller:
+ @puppetclasses = Puppetclass.searchlogic(params[:search]).paginate :page => params[:page], :per_page => 15

Rebased against develop
Changed "searchlogic" to "search"
A future ticket should replace the puppetclass.search mechanism with the tabbed search approach

looking at the latest branch, it includes an import functionality, which is identical to the puppetclass import, can we some how merge them?
this might avoid the need to change the import method in the Environment model.

Applied in changeset 5f6b2196e7bb3283bc2a294cdeba8b59f088812c.
