[PATCH 1/3] cli: add support for --no- prefixed boolean and keyword flag arguments

[William Casarin]

Hey Jani,

Patches look good so far, concept ack for sure.

I've been testing it a bit, I can't seem to make this work in this example:

    ./notmuch count --no-exclude

After some brief investigation it might be because count is using
EXCLUDE_true(1) and EXCLUDE_false(0) which are not equal to
NOTMUCH_EXCLUDE_TRUE(1) and NOTMUCH_EXCLUDE_FALSE(2), but I'm not sure.

Cheers,
William
