Steve McKay 3da8afcf30 Add rudimentary keyboard operation support.
Currently only select-all/copy/paste of files is supported.
Note, I wasn't able to push all code into DirectoryFragment,
as Jeff Sharkey suggested, as it doesn't have direct access
to KeyEvents. Bridged this from StandaloneActivity.
