Subject: [PATCH] fix(gen-rollup-conf): fix globbing issues on Windows (#107)

Windows separators interfere with escaping. For this reason they decided
to use POSIX separators everywhere (they work on Windows by the way). We
don't use escaping at the moment so it's fine to just replace all
escapes (aka Windows separators) by POSIX separators.
