Fancy Kernel r30

- updates from CM10.1 RAMDISK
- create symlink for WiFi workaround on boot
- improve trim on first boot logic
- control groups (cgroups): make systemui real time, move kswapd to a cgroup with less cpu shares and rt runtime
- niceness: lower kblockd and kswapd priority
- small improvement to launcher whitelist wait loop
- remove wifi_drop_workaround value storage upon wifi workaround execution (has been removed from kernel)
