Fix cross-site xhr requests in fs ancestor widget

Cross-site xhr requests in the FS ancestor widget were causing problems.

(familysearch.org instead of www.familysearch.org) fixed the problem.
Closes #13

Refactor architecture for pageAction conversion

Convert the extension into a pageAction with a popup; required a major
refactor. Currently the data object is passed to the controller, then
fetch by the popup and printed on the popup.

Next steps:
* Display URLs in the popup
* Create UI for modifying person info in the popup
* Modify data model passed to controller by widget so that it allows for
multiple parent and spouse relationships

Issue #20
Display search links in popup
