Server-side workaround for frontend's script parameter bug in .21

this should probably work

Merge fixes from .21 branch

revert 9b789de8e5df on branch based on feedback from zorg - seems to be breaking gameplay

Use ghc return value instead of looking for the stderr, do not throw error when an haskell module throws a build failure, e.g. because of false positives like this one (debian/arm*) "You are using a new version of LLVM that hasn't been tested yet! We will try though..."

Find lua 5.1 on fedora machines (taken from fedora hw git)

Fix arm* build failures

Use ghc return value instead of looking for the stderr, do not throw error when an haskell module throws a build failure, e.g. because of false positives like this one (debian/arm*) "You are using a new version of LLVM that hasn't been tested yet! We will try though..."

Was not a good idea in the first place IMO

Workaround bug (each time losing room master status, even when joining mutliple rooms, new instance of NetAmmoSchemeModel created, receiving schemeConfig and modifying its 43rd member, thus the last model which accepts this signal has the string cut down several times, workaround creates copy of qstringlist to avoid modifying shared message instance. Proper fix would delete unneeded instances of NetAmmoSchemeModel, but who cares)

fix amRubber frame positioning fail (probably)

0.9.21 branch

More complete fix for FULLMAPCONFIG message, also add new known protocol versions

Tweak to land texturing. Treat any non-lfBasic as edge
