Modify usage of throw in translations and add API wrappers.

seancribbs commented 10 years ago

Wrapped throw(unset) in API function cuttlefish:unset/0.
Added the throw({invalid, Reason}) protocol with wrapper function cuttlefish:invalid/1. This is used for translations that wish to convey that a configuration is invalid when discovered after the validation phase.
Changed the throw(not_found) from cuttlefish:conf_get/2 into a tuple of {not_found, Variable}. This allows translations to call conf_get for settings that are expected to be present and a useful message about which setting was requested can be included in the error.
