Make more clear how to use the drop down menu, when creating schleuder lists

When creating a list the drop down menu is set to 'random' by default. This led me to believe, that I don't have to fill out the name field - I expected the name to be become some random string. But a value from the dropdown menu has to be changed by the user, to fill the name field. Also selecting 'random' from the dropdown menu doesn't change the value from the name field. Sending the form without a name in the name field leads to the error message 'failed with missing or wrong attr name'. I'd say the default key from the dropdown menu should be 'custom' and selecting it should lead to the name text field be empty. The error message should be more clear and appear near the name text field- using bootstrap it's also possible to inform the user about missing values before the form is sent.
