Radomir Dopieralski d4fb80f500 Fix TemplateSyntaxError in the server-side filetring of node list views
The server-side filtering had two bugs:
* the ip_address is not always available for all nodes
* the fileds used for filtering were not always strings

In addition, I replaced the obsolete glyphicons icon with a Font
Awesome icon for filter.
