Implement generator rules
Introduce a rule attribute "generator" which, if present, specifies
that this rule is used to re-invoke the generator program. Files built
using generator rules are treated specially in two ways: firstly,
they will not be rebuilt if the command line changes; and secondly,
they are not cleaned by default.
A command line flag "-g" is introduced for the clean tool, which
causes it to remove generator files.
Fixes issue #102.
