[gopher] New console gopher client

[Quentin Rameau]

Hello,

I wanted to let you know you can try sacc (short for saccomys) if you're
interested, a simple console gopher client.

There are still a few things to implement yet, move some configuration
options to config.h, add a search feature (there's already a patch),
hanlde window resizing more gracefully, write a manpage, but it should
be quite usable as it is.

You can find it at git://git.fifth.space/sacc (mirrored at the Bitreich
project git://bitreich.org/sacc).

There are two interfaces, a textual UI and a screen UI, wich you can
change in the config.mk.

Feedback welcome, thank you!
