Unlinked JavaScript files.
Added routes for home, about, privacy, and terms.

Reorganized and renamed layout files and view.
Also removed the language files and `$this->translate()` function
calls from the error views to reduce line count in the module's
configuation file - i18n won't be something to be concerned about
for quite a bit of time (if ever).
Cleaned up template mappings and fixed title casing.
