Use IJunctionRestrictionsHook instead of patching

[Elesbaan70]

This eliminates NCR's patches to the JunctionRestrictionsMangager class, so that we can remove redundant deprecated methods without breaking NCR. It is currently a draft PR and cannot be merged until TMPE's planned IJunctionRestrictionsHook API is released to stable. Right now it can be tested by building TMPE from the following branch: https://github.com/Elesbaan70/TMPE/tree/junction-restrictions-hook

Note that this PR includes #54 because the project would not build on English-language systems without that change.
