LSM303DLHC and Magnetometer Support

I just submitted a pull request that adds magnetometer support to the 
sensor API as well as the LSM303DLHC driver: 
https://github.com/apache/incubator-mynewt-core/pull/152

It wasn't clear to me what the right approach is to registering a 
sensor, however, when the sensor contains more than one sensor type: 
https://github.com/microbuilder/incubator-mynewt-core/blob/sensors_branch/hw/drivers/sensors/lsm303dlhc/src/lsm303dlhc.c#L276

If someone on the dev list can perhaps clarify the correct registration 
process, I can update the PR if necessary?

PS: sensor_shell.c currently prints an integer for mag data which isn't 
accurate (it should be a float) but for debug purposes I cast to an 
integer for now due to the lack of %f support in mynewt's libc.
