S110 101b, first attempt at CHDK porting (I don't have the camera).

Based on SX50HS by ERR99. It *should*/*could* boot, everything else is disabled.

*** THIS IS UNFINISHED AND UNTESTED. COMPILE/TRY/USE AT YOUR OWN RISK ***
Add NULL_SUB and MakeDirectory_Fut addresses.
Remove useless asm from S110 loader.

Thanks Nikon- for pointing out the resulting issue (compiler error), not sure on why it was compiling locally though.
This should fix the power-on

found by visual compare with sx50hs
Remove extra line from boot
Probably fixes led blinking, if needed.
Disable HookIntoTaskCreateFunktion, CreateTask_spytask and taskcreatePhySw_my until a successful boot is achieved.
Initial fix for kbd (thanks srsa_4c), leds (thanks Nikon-) and re-enabled core_spytask and kbd task.
