Naming convention unification for roguelike (games) ports and new make target

[t_ziel]

Hello

Please change text "rogue-like" to "roguelike" in all roguelike games, 
so after searching (in description on freshports.org, not in port name!) 
with string "roguelike", _all_ roguelike games are displayed. Maybe this 
can be applied to other ports with "-" in name.

Also perhaps introducing target "make installnoask" is good to avoid 
many compilation questions. Instead of answering lots of questions (make 
install in kde/gnome folder for example) it's easy to type something 
like make install-no-ask and go for coffe (no compilation questions).
