Handling the data for players from rbutil.ini and the build-info data
from the server is closely related. Splitting things up into different
classes only creates tightly coupling, which is unnecessary, and the
need to differentiate between them in the application.
Merge both classes into a single one and rework handling so the
application doesn't have to deal with two separate classes anymore.
Furthermore, change URL templates to use new values from build-info
instead of hard coding them.
