Minstrel - asking for early testers

[imush]

Here is a more substantial update

The App Store version is still the first build I submitted, so it has none of the discovery fixes yet. Your reports also showed me the real cause, which I couldn't see in the iPhone simulator: iOS blocks the multicast search UPnP uses to find devices, unless Apple grants the app a special entitlement. That's why servers show up only sometimes and players like the WiiM and Linn often not at all, and why the app wrongly said it lacked permission when Local Network access was on.

I've applied to Apple for the entitlement; that's what will fix it properly. Meanwhile the next build:
- remembers every server and player it has found and contacts it directly at each start, so once a device has shown up it stays found;
- no longer shows the wrong "no permission" message;
- adds a volume slider on Now Playing when playing on the phone (it follows the side buttons). On a network player the slider was there already when the player reports its volume.

I'll post here when the new build is on TestFlight and when Apple has granted the entitlement.

build 1.0.1(7) uploaded; with testflight, you can try now or wait for review.

I am still waiting for the milticast entitlement which should resolve all issues with device discovery on LAN.
