List preview
Minor fix for preview renderer

Fixed list preview renderer - was loading incorrect IDs
Merge branch 'master' into rd-dev
Added template support to sections

Sections now support multiple templates, defined in a JSON file (this
should eventually get moved to a database definition instead).

REQUIRES database table change - add a varchar field to group_tree
table named template

Also added rudimentary unit test module (go to /test/toast_all to run
basic tests) but new tests must be added.
