#7 Provide an API for configuring things across all forms

[Nigel McNie]

The configuration property 'jsincludepath' is the first such property that should really be set independent of any form. Currently you just set it as a configuration parameter on all forms (with pieform_configure) and it gets picked up and used, but really it should be set independent of any form.

So an API for getting/setting such configuration variables would be nice. It would also be nice if you could somehow set those parameters when pieform_configure is called too.

Aiming to fix this for 0.4.0
