Fix for FM-1173 - http://bugs.adobe.com/jira/browse/FM-1173

Notes:
- when looking for extension, the NetLoader class looked for a "." inside the entire path.
- we updated to look for extension only in the file part of the path

Fix for http://bugs.adobe.com/jira/browse/FM-1167

Note:
- when the resource URL contains a ".f4m" in path part ( ex: http://www.sampple.org/vod/files.f4m/sample_1.f4m ) the resource will be processed twice by the F4MLoader class. When handling a DynamicStreamingResource we check if the resource hasn't already been processed.

Fix (ST-393) The initial index for HDS assets is zero
- the issue appear du the fact that _streamNames array is initialized only after the play method has been called
- until play _streamNames array is null so the quality level is always set to 0
- from now on, the setQualityLevelForStreamName is called inside play method
