Script to install some essential utilities

"Dude, why doesn't this container/server have MC?"

It would be good to have a shell script, dude which installs essential utilities on a server that should always be there. Only a handfull are essential:

1. git
2. curl
3. awk (I mean, really?!)
4. mc
5. tmux

Maybe consider including utilities for #5 as well?

The script should adapt to use the package system / package name used by the host OS, as well, which would make it a bit of a bore to write, but worth it, just for this:

> mc
bash: mc: command not found
> dude
...
> mc
