blinkenlights category should be removed, ports to fall under amusements / graphics

[digibren@…]

I believe it is confusing to have blinkenlights as its own category, that this somehow got in by mistake. In my opinion, all blinkenlights ports should be under amusements or graphics. ​http://darwinports.opendarwin.org/ports/?by=cat&substr=blinkenlights

With all due respect to blinkenlights, it is just not so important that it should have its own category at the same level as lang, comm, etc.

The blinkenlights category is a secondary, "virtual" category in this case; if you look you'll find they are all under graphics as well (which is also the first listed category) and resides in the graphics/ directory.
