Adding options for pageview

[khiemlam]

Hey, I see that the template hardcoded the page tracking options.

I also noticed an older PR that attempted to add an option to disable page tracking, but there hasn't been much movement on that.

I would like to expand on this and add additional options to configure page tracking so that we can specify any of these fields: ga('send', 'pageview', [page], [fieldsObject]);.

I was curious if you think there would be value to this before I work it and submit a PR for it.
