syntax_def for qbasic

["Brian K. White" <linut@squonk.net>]

updated syntax_def for basic/qbasic at
http://www.squonk.net/users/linut/linux/xwpe

I didn't have the const-char quoting character (') defined and so a line
like this:
SPECIAL$='"'

made the whole rest of the file look like a quoted string until the next
" showed up and after that xwpe had a backwards idea about what is
inside vs what is outside the quotes. :)

corrected the line-continuation character even though qbasic
specifically states it doesn't support it, although it does
recognize & ignore it for the purpose of compatibility with other basics
(I had the line-continue character from BBx in there, which although it
is a Basic, has it's own syntax_def so it doesn't need to be here.

also I set better numbers for those last three fields in a syntax_def

btw: is it just me or is "-1 for none" broken or otherwise a falsehood
wrt "column for comment to end of line" (the very last field in a syntax
def, which everyone seems to have set to 1000 for every language, me
included now)

Wish I could dream up a way to use the preprocessor color in basic...
