Simple Notification system

--[[
made by _Exec4tle_#2226 as a FE Scripting Utility!
you can execute loadstring just once
loadstring(game:HttpGet("http://pastebin.com/raw/nfVbXZ6D", true))()
example of usage:
notify("Hello, this is a testing notification!", 10, 17)

notify(   "string",   duration,   fontsize   )

made not for long messages and not recommended to set high values on duration
