* Add support for global verbs These are verbs that are visible for all entities, regardless of their components. This works by adding a new class `GlobalVerb` and a new attribute `GlobalVerbAttribute`. It works in the same way as current verbs, except you can put the verbs class definition anywhere instead of inside a component. Also moved VerbUtility into it's own file since it now has functions for both verbs and global verbs. * Add view variables verb as an example of global verbs * Implement suggested changes Implemented some suggested changes from code review: - Remove unneeded attribute from `GlobalVerb` - Added some useful attributes to `GlobalVerbAttribute` - Moved constants used by both `Verb` and `GlobalVerb` into `VerbUtility` * Reduce duplicate code in VerbSystem (client & server) Greatly reduced the amount of duplicate code for handling component verbs and global verbs separately. * Update engine submodule Need this so client side permissions checks are available.
