[RP] multiple display support broken

[Brian May]

Not sure if this has made its way to ratpoison developers or not.

Latest X-Windows set DISPLAY to :0, not :0.0 and ratpoison will always use :0, even if :0.1 is desired.

See: https://bugs.launchpad.net/ubuntu/+source/ratpoison/+bug/774624

Solution is easy, change the ratpoison code as documented in the bug report:

char * dot;

dot = strrchr(s->display_string, '.');

if (!dot) dot = s->display_string + strlen(s->display_string);

sprintf(dot, ".%i", screen_num);
