Add an invisible authenticate link to the top left
Add faker to Gemfile

more than 24 times, but its very unlikely and can just be repeated in
this case.
Add tuerchen field to imps tabe
Validate uniqueness of tuerchen selection

Allow nil to be able to add new imps.
Show tuerchen in frontend if available and add a filter to search imps
Add task to roll a random distribution of tuerchen for all imps
Add rspec to Gemfile
Add spec_helper and first simple model test
Add factory_girl and database_cleaner to Gemfile
Fix typo in development database config
Get development config directly with one call
