Proposed: Close ISSUE-76, ISSUE-77, and ISSUE-80

These all concern Profiles and, I believe, have been addressed by the  
recent Profiles document.

ISSUE-76: DLP is rolled into OWL-R and clearly Carsten (the issue  
raiser) is on board with OWL-R, thus the doubts raised here are moot.

ISSUE-77: Horn-SHIQ is no longer a profile, thus the issue of which  
precise variant is moot as well.

ISSUE-80: There are many flavors of DL-Lite, for sure, but it seems  
that we are converging on one from the normal editorial process. This  
one isn't mooted, I think, but perhaps could be closed anyway. I  
think it's better that people raise specific issues (e.g., like I  
think DL-Lite-R is better because I need feature foo).

Cheers,
Bijan.
