Enable tracking of formula revisions

Browse Source 
It is useful to be able to prompt upgrades in response to events other
than a version update; for example, when a dependency is updated and its
library version changes, dependents need to be rebuilt to link against
the new library.

Currently we cannot do this automatically, which means a flood of
tickets whenever the library version of a popular library changes.

To address this, we need to track an additional piece of metadata, the
"revision" of the formula, which can be incremented when appropriate to
prompt an upgrade. It can then be reset to zero when the next version
change occurs.
