Break up main.c

[japanoise]

If I'm gonna work on emsys more I need to make it easier to work on, because life is short and I have other hobbies and spend an awful lot of time programming other things (day job).

One idea is to break up main.c. Currently it has kind of a mixed reason to exist, and is 2000 lines long which is painful to work with (a legacy of being based on kilo). Ideally, it would just have int main in it, but I think that's unrealistic. Here's some quick ideas as to how I could break it up:

• Move the terminal code as much as possible into a separate file (term.{c,h}?)
• Move the key handling code (keys.{c,h})
• Move the code to do with initializing the editor struct
• Move the code that handles buffers

Might have to put more shit in headers if I do this, though, argh.

Would also like to document all the files in HACKING.md. Doing that always makes me feel like I've lowered the bus factor a little bit. emsys is not a complicated piece of code, but it is sloppily organized.

totally!
Let me get a couple PRs through first because they are nearly ready

1. Independent window Scrolling #32 window scrolling.
2. zmacs regions #19 visual mark
   also Why uthash? #33 which will be quick
   i might not have time until the weekend
