- edit variables and mass edit variables removed as verbs, merged with view variables

- explosion and emp verbs removed from objects. They are now in the options in view variables for all objects, mobs and turfs.

- Marking objects now gives you feedback on the view variables screen. It also refreshes the screen.
- Warn, prison and unprison verbs removed. Prisoning can be done via player panel. (show player panel verb of the X in the 'player panel' verb. Damn these names, confusing.)
- Banning now has a cancel button on all input screens.
