update to latest template code

These changes don't directly affect network, or don't actually
change the behavior of existing code that network uses (coveralls),
but are intended to sync with the latest template code.

Adds `LSR_PUBLISH_COVERAGE=normal` to `.travis/config.sh` because
network wants to publish coverage normally (as opposed to `strict`
or not at all).
