Hi,

Another new patch for the SAT>IP protocol!
(Sorry for not put a PR... )

This patch is quite simple, but increases the compatibility with a lot of clients.
Some clients incorrectly use the "fe" parameter (Front-End selection). In regular client calls the SAT>IP server handles all physical tuners. So this parameter is only for setting the configuration of static multicast tuners. However, some clients add "&fe=1" in their requests. This is bogus and generates problems inside the TVH.

So, this patch adds a new option in the SAT>IP server configuration. This parameters disables the processing of the "fe" parameter in all RTSP calls. Therefore, it's actually fixing all those bogus clients.

Here the patch:
