Add a setting to enable bracket matching within strings

For the poor saps like me who sometimes end up editing giant strings of SQL, it'd be nice to be able to enable bracket matching within strings. The way Vim does it is that brackets within strings can match other brackets within that same string, but never match brackets that are outside the string and vice-versa (i.e. brackets outside of a string never match brackets inside a string). That way, you get bracket matching within strings while avoiding the issue reported here:
