[feature] allow absolute path to templates (#507)

Only attempt to join the `WebTemplateBaseDir` with the current working
directory if the user has not configured an absolute path to the
template directory.

This changeset also makes a similar change to the testrig, allowing
tests to configure an alternative location for the templates directory.

Fixes #411
