[Gpsbabel-code] trivial patch for osm.c

[Sven G. <li...@fu...>]

Hello,

would you please apply the following trivial patch for osm.c?

Using this patch it is possible to change the created_by tag in osm Output
like this:

gpsbabel -i INTYPE -f INFILE -o osm,created_by=foobar -O out.osm

as well as omit it altogether using an empty string like this:

gpsbabel -i INTYPE -f INFILE -o osm,created_by= -O out.osm

The reason for the patch is that osm output files tend to get very big
is this tag is not omitted.

Regards

Sven
