Commit 35. (Beta Candidate)
1) Completed support for deep data-linking to complex paths which can
 include computed observables returning objects and arrays, etc.
2) Added to observing-paths.html sample to show data-binding to an options
 list under a select, for dynamic insertion and removal of options.
3) Added to and improved the different flavors of the editable-data.html
 sample, taking advantage of the more powerful expression/path binding
 support now available in JsViews and JsObservable.
4) Added additional unit tests for complex scenarios of tag refresh and
 view refresh interplay, and for computed observables.
