[#2] Merge a patch for a proper quotes escaping in

Thanks to Dmitry "hhrhhr" Zaitsev for the patch

Fixes #2
unwarper: Improve breaks unwarping to support an if else break end case

May introduce a dangerous situation with the decompiler not crashing, but
generating an incorrect code. But probably not - if breaks unwarping will
mess things up it will fail just a bit later at the if unwarping phase
