EnumContent; log level can be selected from a popup list.
New EnumContent, with code to load translations in Items. Editable as an AStringContent.
Hacked OptionsMisc to use an EnumContent.
Implemented a EnumContentWidget providing a pop-up list to select from (still needs improving).
Moved IContent to its own module.
ContentExceptions thrown via WDCCheck now.
Fixed a small bug with reloading translations.
