The idea here is to make ufw case insensitive regarding application profiles.

* Simple use-case:
Imagine you have a "Foo" profile:
$ sudo ufw app info Foo or $ sudo ufw app info foo should show the same information.

* If you have the profiles Foo and FoO:
$ sudo ufw app info FoO should refers to FoO and $ sudo app info Foo should refers to Foo
Using sudo ufw app info foo should use one of them (last found profile). To access to the exact profile, the previous usage is to define it with the correct case.

* Same behavior is attented for $ sudo ufw update <profile> and $ sudo ufw allow/deny <profile>
If the foo service is registered, it should not alter the current behavior: using the foo service for $ sudo ufw allow/deny …

* An informational message should be displayed for each command like:
Using "Foo" for "FoO"
