Update to typed-anchors@5c36e53

Fix #1265
Remove _annotator_mapsrc directory

It's not reasonable to be shipping this here. We should be including
the source in the source map files or even including the source map
inline in the source map comment. The Annotator master branch does
this. For now, I'm putting the pressure on here. No source maps until
we get off this damn fork.
Fix tags search for page search

Had inconsistencies with tag and tags.
Unwanted console.log was also removed

Fixes #1267
Change default view to Document

Part of #1231
