The paramater bear_correction is now added to the
request response. It determines whether the dynamic
azimuth correction based on the clients orientation
is applied on the device or not.
Also a bug for retrieving the correct row was fixed.
Debug output removed.
From this change on, the client adds its azimuth measurement
to the get paramters, so the server can do the correction.
Also the response parameter for locally correcting bearing
according to azimuth measurements is respected.
Some comments from copy paste stuff were deleted.
Server now return lastUpdateTZ, so that the requesting
client receives the last update time in his respective
local time (given GPS coordinates are provided).
Lots of print statements still in place.
