queue-builder script should have an option to skip re-scoring builds

[Celso Providelo]

Sometimes people need queue-builder to be quick and just create missing build records and skip slow procedure for re-scoring all builds.

We can be done easily with and workaround in the current script, but the best thing should be integrate code from builddmaster library in content classes and collapse the tasks:

{{{
PubSource -> createBuild -> createBuildQueue -> scoreBuild
}}}

This procedure could be entirely orthogonal based simply on the set of published records we pass throght it .

The big advantage comes when we glue it in the process-accepted task which inserts a restricted group of accepted sources for publication (this procedure is informally known as 'build from accepted')

For the moment this implementation can be done w/o affect the current behaviour of q-b ith the benefit of better integrated/readable/tested code.
