Gem_check

Wrote gem_check to be able to see what gems been installed since fresh install.. or since any point in time I chose to store.

It’s not using git.

• gem_check list all gems not default gems
• gem_check -o keep_state.dat store this point
• gem_check -c keep_state.dat show gems installed after this point

Why?
I wasn’t aware that tty-reader will force upon me an older version of wisper.

Note: I’m aware of rbenv.. I just don’t use it.
