Actually use Copy Files to...

Create a FileCopier and show a custom, non-modal progress dialog when
we're copying files.

Turns out that a QProgressDialog always shows when it's created. This is
by design, so I had to implement one that fits my needs.

Also, a buffer size of 32K (as used in MKVMerger) is way too small to
max out the available bandwidth, so I set it to an (arbitrary) value of
16MB.
