Fix build regression: enable XRANDR support by default

The changes made in b178bed60b5bd8b2c9ed0cbc67fd729ff3820589 used the wrong
variable to set the default state of '--enable-randr' in configure.in, that is fixed now. I
also removed '--enable-randr12': If support for the Xrandr-extension is
available at compile time we set HAVE_RANDR; if there is also support for
Xrandr-1.2 (or higher), we also set HAVE_RANDR1_2 automatically.

Other changes:

* cleaned out public interface of 'class Fluxbox'
* added 'RANDR' to output of 'fluxbox -info'
