"""Loads Actions from the actions directory, and instantiates them.
Args:
filters: list, strings with names of action classes to load. Loader will
skip classes not listed. In the absence of this list no filters are
applied.
log_exceptions: bool, whether to supress exceptions and log their messages
instead.
Returns:
A dictionary of actions, with their names as keys and instaniated Action
classes as their values.
Raises:
AttributeError: if log_exceptions is False and Action classes are missing
ACTION_NAME or FRIENDLY_NAME attributes, or the run method.
