Generic Tag
-----------
This implements a tag that that is mostly useful for testing.

This tag does not implement anything useful, but is a place that can be
used for testing liquid_tags infrastructure, in situations that need
a full lifecycle test.

The first use case is a test of a tag that will pull out data from
the configuration file and make it available during the test.

A tag of
{% generic config <config file variable> %>
will be replaced with the value of that config file in html

Not all config file variables are exposed - the set
of variables are from the LIQUID_CONFIGS setting, which is a list of 
variables to pass to the liquid tags.
