v1.0 boards have noisy accelerometer data caused by interactions
between RF transmission and the accelerometer measurements; this noise
generates a negative bias in the accelerometer readings. The net
effect is that the estimated speed is lower than the actual speed,
causing early an apogee estimate.
By increasing the sigma value for accelerometer data, the kalman
filter 'trusts' the acceleration data less, putting more weight on the
barometer data. This causes the estimated time of apogee to be closer
to the correct value.
This reduces the response to changes in acceleration.
This new value is applied solely to TeleMetrum v1.0 boards. v1.1
boards correct for this error, and hence can use the correct sigma
value for the accelerometer.

Split out sources into separate directories:
core: architecture and product independent bits
cc1111: cc1111-specific code
drivers: architecture independent drivers
product: product-specific sources and Makefile fragments
util: scripts for building stuff
This should have no effect on the built products, but testing is encouraged
