Make writing bears simple again!

[yukiisbored]

Most bears don't require a lot of Python code. Most of them can be declared as simple metadata.

I'm proposing giving developers a way to be able to write bears a lot simpler.

coala-bears is mostly metadata on how to run the linter, how to read it's output, what parameters to be thrown at it, etc.

We can simplify this by do one of the following options:

1. Write our own bear "language"
2. Use Moban

This is probably in the wrong repo, as this would require a new bear loader, and probably should be spec'd in cEP 2.. ?

[yukiisbored]

Sure, gonna write one there.

Actually, on a second thought, Why not make this into a GSoC project for next year :P

[yukiisbored]

Here's the cEP: coala/cEPs#138

[li-boxuan]

Why not migrate this to coala/projects repo so that it has the potential to be a GSoC project?
