Deleting Organizations

[TiSiE]

Currently, there is no way to remove an organization.

As there may be dependent entities (like with users and jobs), we should implement this in two stages

First, removed organization should simply be tagged as deleted and not listed anymore. The profile should also not be displayed anymore.
Related jobs, applications, etc. should not be altered in any way. What we will do with them will be discussed in a separate issue
