SRT Input (srt://:[PORT]) mishandles SRT streamid in incoming connections

[m1tk4]

Two problems:

1. Incoming connections from some encoders will result in broken (unsanitized) stream names. Blackmagic WebPresenter has a fixed streamid that looks like '#!::bmd_uuid=460b34e1-0d3d-4758-ba7e-f9409f79be20,bmd_name=devicename' and that creates unworkable stream names in Mistserver when used with wildcard. "push://" inputs created via SRT protocol (MistOutTSSRT) are being sanitized correctly.

2. All configuration options are ignored and SRT inputs are always using default settings. Particularly annoying is not being able to ignore the streamid - it always treats them as wildcard.

Proposal for a fix for both is in #219
