#30 - resolves logic issue that was preventing deletion of temporary stream recordings. Changes the streamable recording queue in the AudioBroadcaster to find the recording with the earliest start time to prevent situations where a long recording might close out and enter the broadcast queue after a shorter recording that started later, but would have been replayed first.

#30 - changes internal MP3 temporary recording stream management so that the broadcast model manages the recordings and sends the completed recordings to the broadcasters to avoid 2 or more streams recording MP3 files for the same audio call.
...
Note: there is a bug where temporary recordings are not being consistently deleted that I'm still working on.

#30 - adds support for Shoutcast V2 (aka Ultravox 2.1) audio streams.
...
Resolves issue with MP3 framing where the remote server was disconnecting us due to bad MP3 sync. The LAME encoder was sending partial 20 byte MP3 frames initiall, then following with a 144 byte array which contained the remainder of the first frame and the header of the next frame. Adjusted the MP3SilenceGenerator to only emit complete MP3 frames.
This should be the final commit for this feature, pending merge back into master branch.

#30 - changes audio broadcaster to send full/complete MP3 frames instead of partial frames in order to reduce remote server disconnnects due to MP3 frame sync loss on remote server.

#30 - adds support for Shoutcast V1 streaming. Resolves issue where temporary MP3 recording files were not being flushed at the end, causing partial frames to be streamed resulting in repeated remote server connection resets.
...
Note: Shoutcast V1 streaming to a Shoutcast V2.5.x server seems to be problematic. The newer server tracks MP3 boundaries in order to insert advertising and this appears to have problems keeping sync with the MP3 stream. I spent significant time eliminating MP3 framing errors in my code. You can see these 'Bad frame' errors in the sc_serv.log and the shoutcast server will eventually reset the connection after a period of time or after a number of framing errors occur. I anticipate that streaming to a Shoutcast V2 server using the ultravox (ie V2.x) protocol may resolve this issue.

#30 - improves silence frame handling. Appends silence to end of MP3 recordings to round them out to whole second intervals and adds an MP3 silence generator to generate 1 second silence frames each interval when there is no audio to broadcast. Previous approach used static silence frame, but we can't generate an exactly 1 second frame, so the remote server was resetting the connection when it detected that we were sending data at over or under rate.

#72 Enhances management of wildcard values for aliases. Calculates a relative weighting for each wildcard alias id and then orders (smallest to largest) the wildcard values so that when attempting to lookup an id value, it first attempts to look for a direct match and then defaults to iterating the list of wildcard values until it finds the most specific or best matching wildcard value.

Closes #72 - updates alias list to maintain a map of alias id to alias and separate lists for wildcard alias id values. Alias lookup logic is changed to first look for in the alias map for a concrete match to the alias identifier. If an alias is not found, then the list of wildcard alias identifier values is iterated looking for a matching wildcard. If the wildcard is found, then the matching alias is returned from the map.
