Merge issues with the Ex-15 branch

[jamespetts]

Attempting to merge the master branch with the Ex-15 branch produces a few merge errors in GUI code where I do not know the intention of the code well enough to resolve the merges.

Ranran - would you be able to resolve the conflicts? Thank you.

This seems to be a conflict with ceeac's changes.

in boden/wege/weg.h

Code Select Expand

    int get_statistics(way_stat_months month, way_statistics type) const { return statistics[(int)month][(int)type]; }
Is there any intention to make it different from the standard code?

extended was the same except that constant 1 was replaced with a macro.

EDIT:
I think it was probably intended for integration with get_stat().

EDIT2:
I believe the conflict has been resolved.
Test the branch below.
