Please show file size in the file browsers

[laserpanda]

Summary

The file browsers should also show file sizes along with timestamps etc so i can easily see broken frames in a render or if the alembic i'm about to import is enormous

What

Why

because it is the easiest way to see a corrupt frame in a image sequence

Example scenario(s)

I want to know how big a file is before i load it.
