Placeholder for select fields and other

[PatrickRQ]

Hello,

I reported that already but will post that too. We need placeholder configuration for select fields type and other. Let me explain. At the moment when you configure select field with 10 options and check the field to be required the default value will be top one what generates an issue with ignorant users to skip selecting proper option from the selection, so many submissions comes with top option.

So far I had workaround by leaving option key empty and setting value to "select...", however somewhere between 4.4.2 and 4.4.7 IPS changed something and submission passes empty option key as valid one and the submissions come with "select..." option. First of all, empty option key should not be passed successfully trough submission but valid solution would be adding config of placeholder for SELECT and other field types that may require that. Thanks.
