[fix] forgot to sync db dump

[fix] db schema sync (multiple materials and no id field for simple HABTM (or fetching remote object ids would fail))

[fix] renamed 'technique' into more appropriate name 'artwork_support', and update schema and translations (Closes #4)

[evol] created a simple logon system, protected admin pages, and added a logon indicator/link (no user management yet, only a deadend entry in the menu if admin)

[evol] update schema
