Add support for uri/component language

[AlanFoster]

It would be nice to add the following to the plugin; Adding full support for components ie `file:name?fileName=newName" - which should be easier in Camel 2.12.X

Some specific ideas for components are

• Ctrl+click component name, ie 'file' -> Component Declaration
• Ctrl+space support to show available component names
  • Marking invalid when the component can't be found
• ctrl+space support for query string properties and red highlighting if they are invalid
• Specific support for components :
  • file component could open the folder it is polling
  • direct/direct-vm/vm/seda could open the routes they link and perform validation etc

I'm not sure of the best ways of implementing these sorts of things into the plugin, so this is definitely a long term goal.
