Incorrect configuration of LSM303_CTRL_REG4_A #3

I am stupidly settings the same register twice in a row:

writeAccReg(LSM303_CTRL_REG4_A, 0x08); // high resolution output mode
writeAccReg(LSM303_CTRL_REG4_A, 0x20); // 8 g full scale: FS = 10 on DLHC

That could explain why the raw readings were all a multiple of 4: we're not actually using high resolution output mode.
