Change browser behaviour

We have observed that the browser did not show changes. This happens
because the ogClient opens the browser at the beginning and forget
about it. To show correctly the changes ogClient had to restart the
browser every time the menu html changes.

This commit changes the behaviour to restart the browser when the menu
html has changed.
