This function is used internally by Kirby, but you can also use it in your plugins to trigger deprecation warnings.
Example:
function someFunction()
{
    deprecated('`somefunction()` is deprecated, use `anotherFunction()` instead. `someFunction()` will be removed in version x.x.x');
    return 'something';
}
When a user uses the someFunction() function and debugging is enabled, the message passed as parameter will be shown.
