Bjolang's raw strings are strings

Browse source 
Bjolang reads """...""" as a raw string: three or more quotes open it, the
same number close it, and nothing in it is an escape. The grammar has a
string.quoted.triple.bjolang scope for it, so quotes inside one stay inside,
and one over several lines is a string on every line. tests/demo.bjo checks
both, and passes.
