Bundle topology rendering fails gracefully

Bundle topology rendering fails gracefully

If the bundle does not provide proper xy position annotations
on any of the services in its deployer file we do not render
the bundle topology and instead remove the bundle topology
tab, selecting the Charms tab to show the charms the 
bundle contains.

Because we don't have any bundles with proper positions right
now I added the flag `strictBundle` to enable this feature.

Small test change requested, and otherwise code is LGTM.  doing qa now.

File test/test_bundle_details_view.js (right):

https://codereview.appspot.com/14502061/diff/1/test/test_bundle_details_view....
test/test_bundle_details_view.js:188: 'gui-y': ''
I wonder if we should not allow this either.  shrug.

https://codereview.appspot.com/14502061/diff/1/test/test_bundle_details_view....
test/test_bundle_details_view.js:208: view._positionAnnotationsIncluded =
function() {
But this way you are not testing whether _postionAnnotationsIncluded actually
ever can approve something!  :-) Can we just adjust the data instead?
