Optional to automatically go to new page on focus instead of clicking (#127)

Closes #95 

Adds a setting (defaults to enabled) to automatically go to a page when
the navigation drawer item is focused after a brief delay.

Basically, if you open the left nav drawer, and scroll down to "Movies"
after a brief delay (600ms), the app will switch to the Movies page
without having to click.

It can be disabled in advanced settings.
