I currently have a project using an Arduino R3, set up across the room from my computer. This has become quite annoying, as every time I want to push something to the Arduino I have to get up and move either the computer or the Arduino to another location, plug it in, and hope my code works the first time, lest I have to repeat the test over and over again. I am trying to set up an SSH server between my Raspberry Pi 2 and computer so I can just push new sketches over SSH, however, I use my Pi 2 for other projects occasionally and want to purchase a second board specifically for this purpose. Is there a good, cheap, board with wifi built in (besides the Pi 3) that I could use for this? Any suggestions?

Sounds like you want an Arduino Yun instead of an Uno. Or a Dragino Yun Shield that turns your Uno into a Yun.

If you get it working on the Pi2, could you just drop in a Pi Zero ($5) and a cheap USB network adapter ($2)?

Note that your question title asks for "best", but you don't define your criteria. Reading between the lines I suspect "cheapest and adequate" is what you mean.

You could swap out the Arduino for a ESP012, not sure it meets your I/O needs. The new ESPs support over wifi firmware uploads.
