This uses a previously unused S6 flag to save this option persistently.
This should not make S6 import much harder, but should reduce the amount of questions about S4 import.
Also refactor the checks whether the user can ask money for rides or entry. This should make it a lot easier
when our own save format comes around.
This commit expands tabs to spaces (ts=4) in all the files under src/
and test/.
Until now we had two wildly different code styles with C using tabs and
new C++ using spaces. It is painful to maintain as none of the commonly
used tools support this kind of setup and in reality is needless, as we
can simply convert all the sources to spaces and have opened PRs do the
same, where needed.
Additionally, trailing whitespace has been removed.
I noticed there is an extra generate_new_guest which calls park_generate_new_guest. This can be removed in favor of just making park_generate_new_guest public.
This also allows potential in the future for customized trams, such as a group of angry people arriving to trash the park or something like that.
