prolong session TTL on each request

[catamphetamine]

Currently if a user browses a website but doesn't change his session data then the session times out.
I'm proposing this change to your library which fixes the issue:
catamphetamine@c7c13fc
catamphetamine@150d41e

It also prolongs session id http Cookie

If you want to prelong session, why not turn options.rolling to true ?

[catamphetamine]

But what does it do?
The documentation only says that rolling session, always reset the cookie and sessions, defaults to false.
I don't want my session to be reset on every request because the point of the session is to retain data in-between requests.

It does what you want (reset the timeout of session and cookie, not their actual contents) provided it won't be an issue that every request keeps the session alive (potentially including requests triggered by automated polling, which I'll bring up in another issue).
