Update angbadn-x11 to 3.0.1 as suggested in PR pkg/17605.  Some modifications
to the suggested Makefile by myself.

Our previous version was 2.8.3, so the list of changes is rather extensive.
A complete list is available on the packages homepage.

Highlights include (as far as I can tell, not being a user of this package):
- the usual feature enhancements and bug-fixes
- randomized character generation
- improved monster AI
- color coded messages and more sound events
- lots of environmental, monster and player changes
- new MASTER_SITE
- new HOMEPAGE
