CSS rework, aligned view on all pages
removed google JS from pages which do not require it

Fixes #248 - Generalise tab management and search facility

The search facility is now available from all controllers.
The search bar is only displayed if there is a partial
<controller_name>/_search_line.html.erb available.This partial also
describes and implements the possible search parameters for this controller...

Fixes #179 - allow mass assignment of parameters and host groups.

Fixes #132 - Added a clone operation

This clones the AR, attaches clones of the
originals host_parameters and then renders the "new" action, ready for editing.

The host_parameters must not use validate_presence of :host_id when using nested attributes.
Created a hidden :nested attribute to the form to flag this behaviour...

Qualified the fact_selected partial
Added a reset button
Added popup help
