Local customisations of site-wide preferences

Site-level preferences are located in TWiki.TWikiPreferences, however this Main.TWikiPreferences prefs topic has override priority and should be used for local customisations. This allows for easier upgrades as you don't need to worry about the shipped preferences clobbering yours. It's easier to keep a handle on if you only copy over the settings you actually change.

• FINALPREFERENCES locks site-level preferences that are not allowed to be overridden by WebPreferences or user preferences:
  • Set FINALPREFERENCES = ATTACHFILESIZELIMIT, PREVIEWBGIMAGE, WIKITOOLNAME, WIKIHOMEURL, ALLOWROOTCHANGE, DENYROOTCHANGE, TWIKILAYOUTURL, TWIKISTYLEURL, TWIKICOLORSURL, USERSWEB, SYSTEMWEB, DOCWEB
  • Set EXPLICITNUMBERINGPLUGIN_DEBUG = 0
  • Set DELREF_VALID_WEBS = Sandbox, CMSPublic
  • Set WIKIWEBMASTER = twtool.support@cernNOSPAMPLEASE.ch
  • Set VARCACHEPLUGIN_INVALIDATEONCREATE = none
  • Set VARCACHEPLUGIN_INVALIDATEONUPDATE = none
  • Set NOANTISPAM = off
