Themes: Force recompiling common resources when scanning theme

If a theme is re-installed multiple times and in less time than
the 3 minute timout for common resources, it is possible for the
installation to fail because it does not compile the common resources.
This is not something an average user would encounter normally but
theme designers that are working on there theme and constantly
installing updates have a better chance of encountering this situation.
We simply remove the theme from mAvailableCommonResources which will
allow them to be recompiled.

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.
