pageRun hook and .extra.tpl files ignored by inline edit pages

If you edit data in the contact summary view, the save/cancel action returns you to the summary page and load CRM_Contact_Page_Inline_ELEMENT. that should trigger the pageRun hook, alterContent hook, and the .tpl file should be modifiable with and .extra.tpl file — none of these currently are triggered.

I suspect this is because we're constructing the content and fetching the tpl file in a different way than most pages.
