Pluggable Directives Libraries (#395)

Goals

• provide for a framework for introducing additional directives into the system, even from different namespace
• existing directives must not be overridden, nor replaced, alternate versions have to be placed in a different namespace
• zero configuration effort by the user
  • detection of available directives libraries is via the [genshi.libraries.directives] entry point
  • available directives libraries in the system will be automatically loaded by the system
• api for programmatically adding new directives libraries (similar to the current concept of pluggable DirectiveFactory?'s)

Current Development State

• still in early design/prototyping phase

More information will be made available as soon as the initial prototype is working.
