Web bugs jan22nd

A couple of small fixes.

 - #10231 When trying to run a script and you get a "No processor available" you now get a nice message (see image) instead of an exception. Tricky to reproduce

 - #10152 To come into line with Insight, we now use "Run" to refer to PlateAcquisitions in the tree and right-hand panel. Import a Plate with an acquisition that has no name, and you should see 'Run ID' in tree and right panel (compare with Insight). 
 Also, when you click the link icon to get a link to the 'Run' the url should be webclient/?show=run-123
