All facts are numeric, atm. this means that the input should only
accept numbers. it already had the     inputMethodHints:   Qt.ImhFormattedNumbersOnly
option, but for some reason it still accepted letters and symbols.
by adding a     validator: DoubleValidator {} we limit the characters
to numbers only - and if the value is a integer, it will still work.

Tested by adding waypoints on the map & messing with the GPS coordinates.

Map control use different border color based on map type

Initialize espeak in async playback mode and explicitly synchronize after each synth operation in the worker thread.

This mechanism automatically queues data into the correct thread where necessary, otherwise the method is invoked directly with low overhead.

At the same time remove the UDP socket event workaround. It is not a problem.

Also filter solo version string

Also can handle additional components coming through after default
component is complete

Plus other small fixes

this simple patch cleans more than 500 warnings on my build
and it should be really safe to apply since it basically remove
unused variables.

This way we don't need macro-magic to deal with
different operating systems and compilers.
