Aufgabe -> Fähigkeit.
Temporary workaround. Tree page with empty (skill) database is now callable.
I18N properties uses hex-unicode now.
Removed old autocomplete component from skilleditform.
Fixed select mode. Parent is now selectable instead of child.
Fixed edit warning, when editing root skill.
Merge branch 'skilltree' of git.micromata.de:projectforge/projectforge-webapp
