Combine menu_settings_set and menu_settings_set_default and
move to settings.c
Merge pull request #162 from CatalystG/bb_rgui

(BlackBerry) Add initial in-game RGUI support.
Move create_menu_item_label to rmenu_xui.cpp
Remove menu_settings.c
(Blackberry) Add HAVE_RGUI to managed build
(Blackberry) Starts up in RGUI mode now - should (hopefully) allow
for dynamic changing of libretro core and selection of ROM instead
of hardcoded paths.
Update READMEs
Remove frontend_console.h header
(iOS) Move all bluetooth processing to WiiMoteHelper.m; delete BTstackManager.m
(iOS) Add disabled draft of SixAxis support.
(iOS) Move BTstack into a thread. It may still need synchronization with the input buffers, but shouldn't cause crashes or anything.
Fix build for drivers.
Fix Win32 build.
Cleanups to libretro_install_core
(Libretro core management) Cleanups to libretro_install_core
(iOS) Build fix
(RGUI) Add 'Resume Game' option
(PC) Fix RGUI build
(RGUI) Swap Start and Select buttons - Start is more commonly
found on gamepads than Select - Start does 'settings screen switch'
now and Select does 'reset to default' setting
(iOS, BTstack) The thread never returns, it just waits.
(iOS, BTstack) Some cleanup. No more ObjC in the input code.
