Ah, I broke something horribly in the main branch. I'll fix that first, then I'll merge this in.

Oh, I don't think this will work, since the port is hard-coded into the webconfig like you said before.

This might work in the serving of plots, though. I run a server to serve the plots as temporary images to Chrome so they're stored in a different place in memory.

word - I wasn't sure if this was a caching issue on Travis or what, so thanks. +1

Yeah, I was afraid of that. Not sure how to work around that atm.
