	## Flash message system:

	System for automatic and custom messages for users.

	- `app_className` - for automatic msgs to search for msg text
	- `msg` - msg to show or to parse by `app_className`
	- `uiTargetType` - where to show this msg eg. 'default_db_table', 'after_login', 'everywhere'
	- `uiTargetName` - eg. database table name (if from default_db)
	- `userTargetType` - type of users allowed to see this msg eg. 'everyone', 'admin' (ADMIN_LEVEL=0?), 'user', 'group'
	- `userTargetName` - login, group name
	- `actionExecuted` - execution time if msg require user to run specific action (send msg.id in request)
	- `actionNotes` - notes/msgs/dbg for user actions executed from this msg

	Messages created by db triggers must define `app_className` that should parse `msg`. For example to use in FixProjectPath and FixZasobPath to keep correct paths.
