Allow changing of MAX_RECENT in config file

Simple request made by Solarmystic on the forums. Allow you to change
the number of recent isos saved by ppsspp. Default is set to 12.
Reorganize bit the UI
FPS limit : auto-switchable between 30 to 240
Better fit for 800x480
Fix names to be consistent. Moved MAX_RECENT to header file.
Fix permissions on Blackberry.
Currently only the app can modify/delete important data like saves in PSP folder.
On Blackberry, the app is the user account (app_10283782). The currently logged in user is the group (shared_1000). Then other will be all users on the system.
So let's make it that the user can modify their own data.

Allow changing of MAX_RECENT in config file
Accept any negative channel as autoselect.

And fix error codes in sceAudioChReserve().
Auto select the highest available channel.

This is what tests show, and what the PSP does.  It makes sense, since
the game might hardcode 0/1 but some library might use autoselect.  Or
something.
Return an error for invalid audio sample sizes.
Use a separate channel for SRC/Output2.

Tests on the PSP show that all 8 channels can be reserved/used at the
same time as *either* Output2 or SRC (but SRC and Output2 cannot be used
at the same time.)
Error when trying to reserve Output2 twice.
Validate the sample count in SRC and Output2.
Validate the SRC format, and enforce STEREO.

Were these actually outputting audio before?
Correct some logging to use ERROR_LOG.

Oops, was just copy and pasting the other wrong ones.
