Make ArdourFader's scroll handler obey to Alignment increments

Browse Source 
Currently, the scroll handler obeys to the page increment, but instead
of using the step increment for more precise scroll, it uses an
hardcoded one tenth of the page increment.

Use the step increment instead since it has been filled with sensible
values by ArdourFader's users.
