Editor style freecam and Editor mod QoL features/changes

[Notexe]

Editor Mod:

• Selected entity gets added into array in ZSelectionForFreeCameraEditorStyleEntity class which allows the editor style freecam to go to the entity when you hit "Z" (Thanks to @pavledev for helping with the class, I was originally using a custom CPPT/CBLU which wasn't ideal)
• Added a check for s_ImgGuiIO.WantTextInput for entity manipulator keybinds so they don't trigger while in a text input box
• Fixed crash in the OnEntityTransformChange function when entities with physics have the m_bRemovePhysics boolean set to true
• Added snap options for transform, angle and scale gizmo modes

Freecam Mod:

• Editor style freecam toggle (I've included help text in the controls menu as well)
• Add missing "Reset roll" control to help text for standard freecam

Made one final commit which adds a FOV slider to the freecam mod Edit: Feature is way too buggy and the standard freecam has controls for controlling the FOV anyways
