When assigning alias to the command:
1. If there is an alias with the specified name, another one is created even if existing alias has the same command. So it is possible to create unlimited number of doubled aliases
2. If the command already has an alias, and you specify new alias name, a new alias is created but not assigned to the command.
E.g. you have command with alias 'c1', then you change it in User Commands dialog to 'c2'. Alias 'c2' is created. But if you exit this dialog, then enter it again, you will see that command has again 'c1' alias.
Suggestion for p1. If specified alias already exists, then:
1. If it has different command - create new alias
2. If the command is the same - DO NOT create new alias
