[dsmmcken]

Fixes #185, Fixes #1375, Fixes #1488 and other issues with File Explorer

Fixes issue where you couldn't rename a renamed item, and then can't use context menu at all on file explorer.

Fixes issue where triggering a tooltip while renaming would re-render and exit edit mode.

Wires up copy, new file, new folder in context menu.

Renames copy -> copy file

Still a case that fails:

• Right-click a file and select Copy File
• Right-click the new copy and select Delete

It'll try and delete the old file.

Or another case:

• Right-click file, click Delete
• Right-click the now focused file, click Delete

I think when the list updates, we need to update the focusedFilePath as well, since in the above cases the selection change isn't firing again.

I was firing the selection change again when the viewport updated, but re-using the handleSelectionChange wasn't re-fetching the items because the selected range didn't change. I added a force param, but open to better ways of doing it.

This is fine... I think technically we could just use memoization to do the selected items, but no need to change all that and possibly introduce other bugs.
