search: more granular message body searching

"bs:" and "b:" are adapted from mairix(1)

We will also support searching explicitly for quoted vs
non-quoted text via "q:" and "nq:" prefixes since sometimes
readers will not care for quoted text.

In the future, we will support parsing diffs (perhaps when
repobrowse integration is complete).

Note: this roughly doubles the size of the Xapian database due
to the additional information; so this change may not be worth
it.
