Add implicit AND booleans at the end.
This fixes a number of issues in LooqsQuery:
(1) A query like a b c p:(something) would fail, because
a b c get merged into one word. This happens at the end.
lonewords are special and do not become a token immediatly. So previous
logic to add implicit ANDs does not apply.
(2) Negations were also broken with lonewords.
(3) The TokenType enum fields were too narrow to be useful for the bitmask
Independent of that, add support for 'limit:'
Strictly speaking a hack, and we may probably need to
add more chars here.
This mainly fixes the difference between:
"one two"
and c:("one two")
In the first case they are "lonewords", the " does
not get picked up. Then, the search results are something
not expected.
