[HL] The gluon gun issue with cl_lw 1 in single player

[Matthaiks]

@Matthaiks The gluon gun issue with cl_lw 1 in single player will take a bit more work to fix as it requires reworking the animation that runs when prediction is enabled. The reason it works with prediction disabled is that the client itself creates the effects rather than the server so they display properly. With prediction enabled it relies on the animation that plays to do all of the effects but the animation was only created with the beam effects and not the flare effect. If you'd kindly make another issue to track that specific work I'd like to close this one as fixed.
