Pickup polishing (4) And Fly Camera

[mriise]

DO NOT MERGE until #258 lands or a different approach is reached.

im pretty sure @dooly123 had some pickup changes that might be good to wait for to avoid conflicts.

Sorry this PR isnt split better but it just so happened the things i was working on all needed changes at the same time.

Changes

Pickups:

• better (mostly untested) handling of network pickups and stealing
• max desktop zoop distance
• proper velocity on drop
• use direct transform updating when Rigidbody reference is null (or kinematic while held)
• dont hover/interact if UI raycast had a UI target
• when non-kinematic pickup disable gravity while held
• only trigger OnInfluenceEnable/Disable if the value changed state
• default interact range set to 5.0

InputModule:

• movement, crouch, jump pause requests (temporary implementation, see User Input Control Improvements #258)

Camera:

• fly movement
• inherit from pickup to avoid repetitive code
• camera pinning (handheld, playspace, world)
• force camera preview to stay in front of face on desktop
• lots of camera settings for cinematic style movement
• scale based on player height
• Take Photo OnPickupUseDown

BasisParentConstraint:

• blend quaternions better (little testing of this change done)
• index gaurds

TODO

test in vr, havent tried it at all yet.
test net logic

Known Issues

• interact Line renderer does clear and turn off when there is a new UI target.
• desktop control is always pinned in worldspace, ideally this should use a user preference
• camera must be destroyed in between boot mode swapping, i didnt want to bother handling the state transitions. Respawning is easy enough so its fine IMO
• Desktop Camera inital offset takes too long to fetch when spawning, this can lead to odd angles if moving quickly while spawning the camera
• Desktop Camera UI can sometimes block menu UI, not that big of a deal since the exit button is typically still accessible on the camera, though can kinda softlock the menu if combined with the above issue.
