Add rule array-type

[armano2]

This is continuation of #117

[armano2]

I falled into small issue while doing this rule, autofix is not working as it should, and i'm still looking for workaround.

---

eslint is not working correctly when fixer modifies begin and end of node, this prevents fixer of child nodes to be executed.

// input.ts
type foo = Array<Array<Bar>>
// output.ts
type foo = Array<Bar>[]

fixer is going to be applied only to first Array not to both

---

^ why?

eslint applies fixer in sorted order base on range, when fix return array of fixers output is computed for entire range of all fixers with filled gaps.

If token was already modified new changes are not going to be applied on it.

---

possible solution:

• traverse all child nodes and fix all arrays in one fixer
• ignore this issue

@bradzacher what do you want me to do with fixer?

i did some digging and looks like its working when you run it from cli but not in tests

few nits but otherwise looks good.
blocking on parameterised messages.

Is there a reason you chose to use static messages instead?
