Nested import handling

[jerekshoe]

This PR should address #28

Changes

This PR does 3 things:

1. When bundling, recursively get the order of css imports
2. When watching, changes to import order are now handled
3. Adds a new test for nested imports

Illustration

Import Structure

main.js
|---- b.js
|     |---- b.css
|---- r.css
|---- g.css

Output Structure

b.css
r.css
g.css

Notes

• Transform only gets called for changed files
• The order in which transport is called on changed files is not guaranteed

I'm not actively using this, so if someone else can confirm that this is what they expect, I will merge this.

Do you mind moving helper functions to the bottom of the file?

Also, I prefer

Suggested change

	var arraysEqual = function(a, b) {
	function arraysEqual(a, b) {

Would it be ok if I created a util.js (or similar) file?

[jerekshoe]

If not, I will move to the bottom of the file as suggested

[thgh]

Bottom seems fine :-)

The base branch was changed.
