I've changed tasksubmitter to accept a "thing" and "action" rather than a single URL. This seems more in keeping with
propertyControl, and eliminates the need for loads of
computed properties.
I've also deleted (rather than just commenting out) chunks of the web app that are no longer in use. These may be
reinstated in the future - but we can get them from git
history. It's less confusing not to have vestigial
code in the repo.
This builds OK but is not, as yet, tested with hardware.
I had intended to store a ConsumedThing for each Thing, in
a module in the store. Until that is possible (will require some
more attention to dependency management) I will just store
the TDs instead.
This commit includes a lot of the code I wrote for node-wot use,
but without any dependence on node-wot.
