Update TypeScript to latest stable version (#28)

TypeScript has been updated to the latest stable version. Our standard
module TypeScript configuration has been brought over from the module
template as well, including a separate configuration file for
production builds (as opposed to the root file used for things like
tests).

A `build:clean` has been added as well, for consistency with the module
template.
