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.
