[sailfish-browser] Update toolbar to the new design

This doesn't contain yet double height toolbar for portrait
orientation. Double height toolbar will show title and url
for user while page is loading.

Toolbar is now animated with discrete y transition instead
of opacity animation. Logic is the same as it was previous
except the gesture threshold is cut to half.
