Issue #283

Updates Icecast TCP broadcaster to correctly handle content type:text/html
message that normally follows mount point in use error received from
broadcastify.

Changes mount point in use broadcast state to be a temporary error so that
the stream will attempt to reconnect after receiving this error.

Updates logging to include memory allocation/usage metrics with each
logging entry in order to support debugging issues related to high
memory usage situations.  Updates initial application logging to better
identify the host system operating environment.
