Call recording encoder/format choice 3/3

PS1: Adds a user option between WB AMR (the default) or HE-AAC for the encoding
 of call recording audio. Also changes the output format of the file
 appropriately (WB AMR now uses the WB_AMR output format and HE_AAC chooses the
 MPEG_4 output. File extensions are adjust accordingly as well).

This was in reponse to people complaining the quality of call recording audio
 is poor. It's noticibly better using HE-AAC, but filesizes are larger.

PS2: Removed Whitespace
