Condition text aggregation (texts in DB scheme):
   (b1) unary operator: operator + value1

   (b2) binary operator: value
      > 4 AND < 7  (... in between)
      >= 4 AND <= 7  (... in between inclusive)
      < 4 OR > 7  (... outside of)

1. remove Amount (LATER POSSIBLY: aggregate into T. Type: 'at least # of devices' ==> '> 3 dev')
2. remove Ev. Int.
3. Field order:
 - Alert Id
 - Name
 - Type
 - Grp ID
 - Dev ID
 - Spec
 - Aggreg. condition
 - Active
 - Triggered
 - Counter
 - Edit
 - Delete (confirmation screen)

EDIT screen:

 - operator before values
 - Enabled by default
 - remove Oper second
 - textual changes: 
   - 'Num first' => 'Value'
   - 'Num second' => '2nd value'
 + add evaluation interval (in seconds, minimum is 120)
 + (FUTURE) add notification interval (in minutes, minimum depends on license ;-) - 120 if unknown (free license))

LATER POSSIBLY:
 - unary: 'Value'
 - binary: 'Start', 'End'


Some fo the DETAILS of the alerts are not mentioned anywhere. While they are not (yet) being stored in the database, ale least the 'triggered since' and 'last notification time' are interesting enough to be shown on some datails screen.
