New port needs commit -- replex

[Emyr Thomas]

I have created a port for replex[1], see ticket #13664
Could someone please review and commit?

Replex was created to remultiplex transport stream (TS) data taken from a DVB
source. The result is supposed to be a program stream (PS) that can be
used to be burned to a DVD (with dvdauthor).
Replex can also remultiplex other PSs and AVIs with MPEG2 content.

This is my first port, so it's probably worth checking that I haven't
made any boo-boo's.

Thanks
