[orion-dev] Stray commas

[John Arthorne <John_Arthorne@xxxxxxxxxx>]

One of the build problems last night was
an an extra trailing comma in an object literal. These are tolerated by
browsers but are illegal and cause the closure compiler in our build to
fail. This is just a reminder that we should all be using the Orion _javascript_
editor, which correctly reports trailing commas as illegal. Please don't
commit any JS file that has errors showing in the Orion editor. These problems
are trivial to catch at editing time but can be really difficult to track
down in the build (Simon was tracking this down until 1am last night).
