LP: #975692 phase 1

 * Rework list style management.  No more style priorities or matching..  Now,
   you name a style explicitly to apply and that's it.
 * create_list() now takes a `style` argument.
 * config file now names both a default style to use, and a set of paths to
   scan for IStyle instances.  (This could be a model for other plugins.)
 * added IMailingList.style_name to record the last style applied, but this is
   going to be removed in subsequent revisions.

Also:
 * Move find_components() and scan_module() from app/finder.py to
   utilities/modules.py
 * Cleaned up lifecycle.rst for better documentation.  Some tests moved to
   test_lifecycle.py.
 * Remove some unnecessary test tearDown() code.
