Move use statements to beginning of widgets.rs

I think the convention is to put use statements (including pub use) towards the top of the file under the mod statements.

I usually put mod after use so I tried to find some official guidance here and found this in the rust style guide.

Put imports before module declarations

Oh you're absolutely right. I spaced on that because they're pub use statements, but they also go at the top generally.
