GotoUdon - 1.4.0 New SDK, emulation and fixes

NOTE: This version should be installed by first removing old version. (might work without)
NOTE2: This version will reset your GotoUdon settings.

Emulation was restored with this version, but its still very basic, mostly intended for simple tests for player join/leave events.
Vrchat sdk versions checks were changed to use my own version number instead to prevent issues.

This version contains also many small improvements to general way how client manager works.

Sorry for long time with no updates ;) I hope someone still need this.
