Here's an image of my Digilent Coolrunner II development kit:
Those connectors on the backside are 6×2, female, and seem to be on .1" pitch. Are these standard, and where could I buy the male counterparts? Much obliged. Just a few words to search on is all I need. '6×2 electronic connector' didn't cut it.

That looks like the standard of standard connectors the 100 mil header, they may be older than engineering itself ;) Most connector manufacturers make them in various, lengths, platings, and angle positions. You could order a 6x2 Samtec version from digikey for $1.63 http://www.digikey.com/product-detail/en/TD-103-T-A/SAM1114-03-ND/1105555
It says no stock, value add, but that just means they cut them to your length to order. Pick USPS shipping if you want the best shipping deal.
Samtec is also great about sending out samples for free so if you only need a few you can request samples from their website. Here's a link to their page for 100 mil connectors. http://www.samtec.com/standardboardtoboard/100_pitch_square.aspx
Molex also makes them under the CGrid or CGrid III name: http://www.molex.com/molex/products/family?key=cgrid_iii&channel=products&chanName=family&pageTitle=Introduction
Those are what I usually use, although I do really like Samtec as well. Keep in mind when ordering they come in different types of platting (and different plating thicknesses). So if this is proto or a hobby project you'll want to get either the thinest gold or no gold to keep the price down. This is an extremely common part so they should be easy to find.
One last tip is they're easy to cut to the size you want so I usually just buy a bag of really long ones, say 32 x 2 and then cut them to size as needed. They're pretty useful in the lab for making test points or connectors on the fly.
Good Luck!
