hangman warnings during check

File 'tsgames/R/hangman.R':
  assign(".hangmanoptions", c(wins = 0, losses = 0), envir = .GlobalEnv)
  assign(".hangmanoptions", .hangmanoptions + c(1, 0), envir = .GlobalEnv)

There are some warnings due to hangman. The DICTIONARY warning should be easy enough to correct. I think we could get around the other warnings about writing to .GlobalEnv by defining an environment for hangmanoptions and using that instead of the global environment.

I get the following notes that need to be addressed in scoRched and hangman. Not sure how to approach. In the past if you set the variable to NULL first this fixes this problem but here it's defined int he global environment. This is likely what Dason means by define a new environment:
