Suggestion: Replace Reachability with modern version

[Voley]

There is an issue when using FreeStreamer - if the project uses Reachability (https://github.com/tonymillion/Reachability) the project will fail with linker error, since conflicting Reachabilities.

This version is fully backwards compatible and offers blocks as an addition.
I replaced the version in FreeStreamer with the new one and everything seems to work fine.

@Voley The latest version has solved this problem. You can try it.

Actually @mps noticed that @tonymillion's Reachability doesn't seem to be fully compatible:

Error example: SCNetworkReachabilitySetDispatchQueue() failed: Invalid argument

So, yes, with pods the dependency is handled OK but there may be some incompatibility issues.

It looks like it is a known bug in @tonymillion's Reachability implementation: tonymillion/Reachability#63

Calling start/stopNotifier multiple times is not possible.

Seems to work OK with the old/new Reachability with the workaround 600f69d

Should be OK to close.
