* return all wikiparserrules w/o operand
* simpler layout & code / updated instruction details
Also wanted to link each rule to the official docs using a dictionary at
`$:/language/Docs/ParserRules/`. However, without #2194 this is not
doable.
* Ignore parser rule configuration in safe mode
* Made text translatable
* Added new setting for camelcase links
* Added warning on parser rule configuration tab
