v1.2.0 - Map editor improvements

• Ported the feature to control camera speed with the mouse scroll wheel.
• Ported most of the camera settings menu in the map editor menu bar.
• Added a new option to the map editor menu bar at Editor > Settings > Rotate bounding boxes. Causes the bounding boxes of objects to be rotated based on their orient property. Useful to see how objects that don't have meshes are oriented. It's disabled by default.
• The inspector now shows the orientation matrix under the pitch/yaw/roll sliders in case manual edits are needed, and so people can make cursed maps if they want to.
• Added a button above the pitch/yaw/roll sliders to reset the objects rotation. This returns pitch/yaw/roll to zero and gives the object the default/identity matrix. This is a temporary fix to the pitch/yaw/roll values getting out of sync with the matrix.
