[Combine] Atari Inc / Corporation

There's currently 3 pages for Atari. 
1) Atari Inc @  www.giantbomb.com/atari-inc/65-182/
2) Atari Corporation  @  www.giantbomb.com/atari-corporation/65-548/
3) Atari @  www.giantbomb.com/atari/65-634/ 
 
Should either all be combined into the #1 link (Atari, Inc). However, the #3 link brings up the point that they reference only to Atari of the "old" days. #2 Link should definitely be deleted for redundancy, however games linked to these pages (which is a lot) may be lost. 
 
Not a small effort imo, but will streamline categorizing for people in the future instead of choosing between three ATARI company pages.
