Math: moved matrix multiple operations to .cpp file
...
this means we only link this in once, rather than for every use of
matrix multiply, which saves us some flash space
We need to be careful not to put large pieces of code in template
headers, as if the operation is used a lot, it costs us a lot of code
space

AP_Declination: Added method set_initial_location

This will set the declination based on lat/lon if the user has
not yet saved one to the EEPROM, OR if they have specified via the
config parameter that they want it to overwrite the declination every
3D fix.
