File Browser/BPY: Expose list of selected files in context

Since recently it's possible to query the active file (as object, not
just the name), but it's quite useful for scripting to have access to
all selected files.
This introduces `bpy.context.selected_files`, returning a list of file
objects representing files in the File Browser.
