Added alot of existing pull requests into current script, added jitter(ish), change output, added to readme

[ghost]

• added revshell delay idea and my own jitter to go with it (i know the jitter is janky and could be done better :) )
• updated readme where needed for usage
• added comments for fireprox usage in script w/examples
• made script output cleaner when run (colors, colors for everyone and less wordy)
• Hand merged existing pull requests where i thought useful to make script better than it already was quickly
• added user-agent string 'spoofing' into cmdline arg and script. so it wont send powershell string
• added credits for pulls i hand merged in this pull to readme at bottom (could fix with contributor file but i had to get this working on a tight timeline so i did not)
• did not change client-id value in bodyparams variable
  -fixed output error since last pull (closed and reopened)

again great script hope this helps.
