A simple fix of setting the environment paths before the repositories
are loaded.

Added a changelog entry

This commit implements smooth nearest neighbor scaling, this scaling method looks sharper than linear scaling and not deformed like NN scaling.

When loading a savegame, its filename gets stored as gScenarioFileName.
However, that isn't necessarily the same name as the filename of the
corresponding scenario (or any, for that matter, due to the different
file extension). This broke highscores, so for savegames we have to
take the scenario filename stored in the file.

Add null check for map_get_first_element_at in map_get_park_entrance_element_at

Title editor sequence selection now defaults to current preset. This is
only after the first time the window is opened. Afterwards it keeps the
last selection.

Land rights tool no longer cares if part of the available land is
unavailable for purchase. It will not even through an error when none of
the tiles are available. Just like other tools.

Added a changelog entry.

This increments the network version.

The viewport had a 1x1 spacing before the bottom right border was
reached.

For some RCT2 parks the scenario name in the sv6 file is wrong, so take the real filename.
