moved chomp line to beginning of parse

As far as I know all lines can be chomped without causing problems with
our regex and generation.

I've also added some commented out code with an idea how to preprocess
multiple braces on one line.  I'm still not sure how to integrate it
because of how the slurp/next/last/backtrack stuff works and how
recursive parsing factors in.  I'll try to figure out an elegant way to
tie it all together.
working on the braces feature

This broke a few things so this commit doesn't work, but I want to put
an interim commit before trying to fix the regex
All tests pass again.

I'm going to run some large production dhcpd.conf files through to make
sure it doesn't do anything weird.  I'm glad the tests pass but I'm
worried about edge cases I may have forgotten to test.
