Subject: [PATCH] logik : add a brand new game

logik is also known as mastermind. There is an optionnal flag to compile
with :
`make logik COLORMODE=BGCOLOR`
**NOTE** : only tested on FreeBSD, it suppose to work on UNIX-like. One
of the needed dependency is :
```
/bin/stty raw
/bin/stty cooked
```
it's hard coded in the line 75, 134 and 140.
