#7 New forms WIP

* adds saving functionality for new intervention form
* refactors new identifier generating, so a pre-generated identifier from a new element form will be checked again before saving
* adds css fixes for disturbing input field:focus bugs
* adds missing csrf token to new collapsible form
* adds/updates translations
* introduces mark_as_deleted as only marking instead of using delete() which will really delete from the db
