ZF-2899: Zend_Filter / Zend_Validate setDefaultNamespaces

Description

While creating my own filters and validators it's very annoying to have to add the name spaces everytime I use Zend_Filter::get() or Zend_Validate::is().

It would be much nicer to have a setDefaultNamespaces, which would allow namespaces for Zend_Filter and one for Zend_Vailidate to be setup in the bootstrap.

Comments

An example of how I would implement DefaultNamespaces

Matthew, could you please evaluate this issue? I'm wondering how such functionality would work with Zend_Application, too.
