gpx2svg 0.2.0 released

After quite some time, a few things changed, so let's do another release of of gpx2svg, the program to convert GPX to SVG. So what's new?

• gpx2svg now supports true-scale conversion using a WGS84 projection (see the --help output on how to use it). Big thanks to Hans Busch for contributing the respective code!
• The project is now licensed under the terms of the GPLv3 or later (and uses SPDX license identifiers).
• Let's use reasonable versioning from now on. Okay, we keep version 0 for now, but bugfix releases (x.y.*) are now easiliy distinguishable from releases adding new features (x.*.0).

Not much more to say, the code still does the one thing it was written to do ;-) Thanks again to Hans for supplying the initial patch! Have a lot of fun with gpx2svg!
