[FEATURE] Input to set player model

[DESTROYGIRL]

Description

Previously it was possible to change a players model by changing the modelindex value on the player entity. This is no longer functional in the new engine version and was very tedious to work with, so I think it would be better to create some new functionality for this rather than fixing the old method

Proposed Solution

Give the player entity a new input, say SetPlayerModel, with the parameter being a the path to the MDL file that the player's model should switch to when recieving this input
