Add CDATA inside <script>
changed travis min version from 0.8 to 0.9
added `include` option; added regex capability for `include` and `ignore`.
Implements disableAcceptEncoding option to disable gzip encoding of response.

Livereload is not gzip-aware, so gzipped websites are not properly parsed on the "write" function.
Implementing gzip is both costly (performance wise), given that it would need to uncompress and compress every gzipped response, and difficult, given that "write" is synchronous and node zlib methods are all async.
Therefore, a simpler solution for development purposes is to simply remove que "Accept-Encoding" header sent by the browser.
