[PATCH] Return maximum of 150 results

[James Vasile]

Display a maximum of 150 results when searching for messages.  This
prevents client lag when searches return thousands of results you'll
never look at (use the Filter command to cut down results that exceed
150).

Number of results can be changed by setting notmuch-max-results.

This patch depends on notmuch supporting the --last-index option, a
patch for which I emailed to the list earlier this evening.
