Continuing work to test/validate builder commands as well as renaming them to follow the @ prefix convention.
macl -> @macl
bulistcmds -> @bulistcmds
dropped @setattr in favor of default @set which is more featureful
removed 'bu' prefix aliases for @door and @doorpair
sethelp -> @sethelp
unlink -> @unlink
here -> @here
... more to update but it's a start.
Discovered a bug in Evennia where system commands would be doubled in some cases (especially the EvMore pager). Fixed in our install via a monkey patch and also contributed it upstream to Evennia:main so hopefully in some future version we can get rid of our local patch.
