V0.16-2 just hit the repositories

What's new ?

The main improvements are in the batch tile download functionality. I have added support for socket reuse, which is faster and puts less strain on network infrastructure during large downloads.

I have also reworked the inner thread logic, so the download/size estimation starts immediately after pressing the corresponding button/area and it also should now be much faster.

The size estimation run now also removes tiles that are locally available (in the db/file-system) and removes them from the download queue - you can see how the estimated number of needed tiles decreases each time it finds a locally available tile.

Other than the batch tile feature, I have added basic logging support, that can be enabled from "options>debug->Log modRana stdout to file". A file named modrana_stdout.log.txt should then appear in MyDocs with the terminal output from the last modRana run. The rounding bug for imperial units in navigation should be now fixed and sqlite tile storage should be more stable.
