Feature request: arrow keys to scroll through history

[aaronjanse]

It would be cool if users could do:

1. reload
2. see error
3. press up arrow
4. type confirm to run reload confirm

This request is actually to add readline support mcrcon so that arrow keys can be used to go back and forth through commandline history. I'm accustomed to having this in just about every cli app, and would love to see it in mcrcon as well.

I really would like to see every CLI tool use readline.

In the meantime, you can add readline support to cli tools that don't support readline by using 'rlwrap' -- a readline wrapper as follows:

rlwrap mcrcon -H 127.0.0.1 -P 25575 -p $PASSWORD -t

I just coincidentally submitted a pull request adding readline support (for linux and osx at least). Did not know about the rlwrap command. Learn something new.
