Sequences with protection level >0 can be deleted in Search and Query

[fog]

Sequences can be deleted from the database using the 'Delete Listed' button in Search and Query even if the sequence has S3 in ali_16S/data and my protectin in ARB_NT is 0

Security concept of ARBDB is much too complicated:

• There are 3 kinds of security levels (READ, WRITE and DELETE):
  • Only the WRITE level is visible to .
  • The READ security isn't used at all
  • The DELETE security is only used when deleting
• When deleting containers (e.g. species) only the DELETE security is checked. Problems arise, because the DELETE security is not increased, when changing WRITE security levels of sub-fields

More transparent concept:

• only use ONE security level (WRITE security)
• when setting security of a field or container
  • increase security of parent container if lower
  • decrease security of parent container if higher (use security of most secure child)

Other things needed:

• database check at startup to correct all security levels
