* Add grouping of preconditions to allow for flexible precondition logic. * Fix checking Module Preconditions twice (and none of the command's own) * Fix command preconditions group 0 looping over every other precondition anyway #whoopsies * Use custom message when a non-zero Precondition Group fails. * Fix doc comment rendering. * Refactor loops into local function * Considering a new result type * Switch to IReadOnlyCollection<T> and fix compiler errors * Revert PreconditionResult -> IResult in return types - Change PreconditionResult to a class that PreconditionGroupResult inherits. * Feedback on property name. * Change grouping type int -> string * Explicitly use an ordinal StringComparer * Full stops on error messages * Remove some sillyness. * Remove unneeded using.
