[Buildroot] [PATCH] introducing transmission bittorrent client

[Marcus Osdoba <marcus.osdoba@googlemail.com>]

the client has an excellent webinterface
and seems to be ideal for headless systems,
the statedirectory is stored in /var/transmission which links to tmp,
the user should provide a writable config direcory

Based on work by: Kelvin Cheung <keguang.zhang@gmail.com>
