Add IPC socket

[vilhalmer]

This could be useful for a few things, off the top of my head:

• Changing the image on the fly
• Pausing/resuming animation (for example, while the desktop is mostly covered)
• Ok, maybe just two things

With regards to:

Changing the image on the fly

It would be nice to see support for transitions.

I haven't put any thought into transitions, though I can definitely see them being a desirable feature. I'll have to ponder that a bit.

This is nearly done as of 88746bf6. I'm going to leave it open until I fix up the issues with partial application when property validation fails, and until I write up a manpage for ogurictl. Progress!

Hello, is this still an area of active development? looks like Oguri has generally stalled, but I hope I'm wrong since it's such a great project so far!
