HLS/HTTP fixes:

- Optimize URIReader class to not close connections if not needed
- reConnector now works for non-GET requests with GET params
- Chunk sending mode correctly kept for HLS
- Removed lots of H.Clean() from HLS that weren't needed
- Improved HTTP output class request handling logic
- Removed firstRun from HTTP output class; no longer needed
