This introduces an abstract base class that command line tools need to
inherit from. It provides a simple framework for registering accepted
command line options and provides commonly needed things like help
output and colored text.

This very basic test ensures that the useCache method works as
expected for simple scenarios. This test case fails without commit
a8795974 and then also triggers the
warning that was introduced in bc2ddb54

This adds a warning in the case that the default action is not null but
also not callable which can happen when the supplied method is not
public.

Caching had been completely broken (disabled) for caches with events
because the default event handler (cache::_useCache()) was protected and
thus couldn't be executed by the event handler. This was broken in
c59b3e00
