Added date.js as fallback include. When using the en_US locale date.js will not be loaded in yaft.js since the locale from sakai will be empty where it tries to load.
Every time a forum with availability settings is edited the hour is decreased with one hour, removing these lines will fix this.
Removed fallback include for Date.js and added the load of fallback in
yaft.js instead since double inlcudes of Date.js messed things up.
cleanup
Fixed Swedish translation.
