Add pointing (#1435)

* Add pointing keybind and simple message * Add turning the player when pointing * Add pointing arrow * Make the popup message appear on the pointing entity * Add pointing to tiles and space and proper grammar * Move pointing bind from HandsSystem to PointingSystem * Add more messages for pointing depending on the viewer perspective * Fix non nullable reference type * Serialize pointing arrow duration * Serialize pointing arrow step and add summaries * Make arrow speed serializable and make it depend on frame time * Add 0.2 second delay between pointings * Add pointing arrow yaml examples * Add the ability for pointing arrows to be rogue * Remove rogue package reference * Add point to verb https://cdn.discordapp.com/attachments/313107470031650816/735268651636228197/unknown.png * Add shift middle clicking an entity in the verb menu to point at it * Add VV to PointingArrowComponent * Increase pointing delay from 0.2 to 0.5 seconds * Address reviews * Fix nullability errors * Separate pointing and rogue pointing code * Fix rogue pointing arrow visuals * Made rogue pointing arrow rotation adjustment readable for mortals * Make rogue pointing arrows less destructive * Cleanup more of the rogue pointing arrow code
