Reload elements tab

When previewing the DOM in the elements tab there is no feature to reload the current elements in the dom. Quite often things are added to the dom programmatically.

The only way to see this reflected in the Elements tab is to hit remote select toggle your target again, and then return to the elements tab.

Live reloading on changes would probably have its cost. However just having a 'reload' button to update the elements tab would save a lot of clicking around.

Cheers, this project has saved me many hours in debugging Android 4.1 issues.
