Initial verb / REST support
Bug: Did not break soon enough: Even if body returned content, we
continued.
Added Controller comment
Asset class rework to be included, instead of inherited (as before)
Do not call Error404 twice if even it doesn't have the resource
Add gem build & install script
Corrected the update macro (put & patch)
Special rule for Float capture (do not accept scientific notation, etc...)
Check for nil explicitly (false should get displayed)
