Map: remove LocationInformationWidget::coordinatesChanged signal

Browse source 
This was used by LocationInformationWidget to instruct the map
that the coordinates of the current dive site has changed.
There is no reason why this couldn't be a function call, as no
other object ever connect()s to this signal. In fact, such a
function already exists viz. updateLocationOnMap.

Therefore, replace the signal by a simple function call.

Moreover, the uuid and coordinates of the dive site were transported
via the global "displayed_dive_site" object. Instead, pass this
information in the parameters of the function. This makes it
easier to reason about data- and control-flow.
