Adding example config for customized templates
Moved template files

Within the package directory makes a bit more sense I think
Reflect the template move and install

Before, templates would be shipped in the source tarball but wouldn't be
installed in the package directory. This way the source tarball and the
finall installed egg (sic) will have the templates available.
Template directories

This way we point the template directory to the shipped templates (part
of the *package data*) but we can also override the template lookup with
an entry in the ini file pointing to a given location. Dropping files in
this custom location will use these entries instead of the ones shipped
with the package.
