rename to git-open

[gerep]

@Yeraze suggested to change the name to git-open and instead of using opengit, use git open

@jdickey @caruccio @JustinAiken @dennym @DamirSvrtan, sorry for pinging you all but since you are the most interested in this project I had to warn you.

Following @Yeraze suggestion, I've renamed the script to git-open so now you can use it like: git open, friendly right? 😄

👍 That's a better name

[jdickey]

👍 Agreed. I'll have the mental muscle memory remapped in a month or so 👿
