On what level should the providers be chosen

[Maciej Piechotka]

Currently the providers are chosen on the Merb::Global level (i.e. per
module -> per controller). However it is no longer possible if we would
like to implement ticket #25
(http://trac.ikonoklastik.com/merb_global/ticket/25).

What seems to be inevitable evolution is to remove them from the
controllers. However where to put them?

1. Per-locale level: Is there any need?
2. Global level: Seems reasonable
3. Other?

What do You think?
