Move FileInput from ui-forms to ui-core about ui HOT 2 CLOSED

By extracting the ui-forms component to ui-core, we will be effectively be introducing that behaviour anyway, so that todo can be removed.

I think this is probably a good idea for the reasons @Mohammer5 mentions. There are a few things to keep in mind though:

• This FileInputWithList component will not be as composable as the other components we have in ui-core. It won't accept any children, and instead render FileListItems based on an array of File instances.
• Most of our ui-core components are sort of analogue to native elements, but this one work a bit differently (i.e. appending files to a list and being able to remove individual entries) to conform to our design specs.

Just to clarify my stance on this: I am mentioning the points above because these were things that crossed my mind when discussing this with @Mohammer5. I don't really have any objections to introducing FileInputWithList to ui-core, provided we also keep the current File* components. It's probably a wise move.

Finally I'd like to add one correction on the ToDo list:

Make component add files instead of replace when already having files

By extracting the ui-forms component to ui-core, we will be effectively be introducing that behaviour anyway, so that todo can be removed.
