update some gems, replace before_filter / after_filter by before_action / after_action
and some more config changes (mostly commented out) and scripts generated by rails app:update task
first make everything work locally with rails 5.0
test do not pass on CI yet because the test task has to be rewritten
- update dependecies
- run rails app:update task: update config, generate intitializers etc.
- the method hide_action is not available in rails anymore
- ActionController::Parameters have to be converted to a hash
- protect_from_forgery now defaults to prepend:false
this is recommended since rails4. This way binstubs can be
kept consistent accross installations.
Did the upgrade dance and removed bin from .gitignore.
