Allow for expansion and aliasing on global hooks

[twolfson]

Currently, due to a design flaw, we either have to hack with the global variable or break up object-fusion2 into a fuser module and an expansion/alias module.

The issue is that the global hooks need to handle expansion just like everyone else but nobody uses them as descriptions in their outlines (for obvious reasons). We could hackishly add the temporary description but it gets ugly fast when pulling that out.

The proper abstraction is to make the expansion of content something we can do without the fusing step.

Bonus features of this:

• global before can use another method in its expansion
• another method can use global before in its expansion

If we get it right, then in #13 we can call before as a method. crazy.

We have failing tests on dev/implement.complex.global.hooks to resume later.

[twolfson]

When we break out the new module, I want to flatten all expanded hooks into one function and make all hooks into objects, so that renderBatch can be super-simple.

[twolfson]

Make sure that this new module uses flat files as its test suite.

[twolfson]

When this breakout happens, open an issue to nuke proxies from object-fusion2.

[twolfson]

The new module will take the content object and expand, alias, and flatten all values recursively.

[twolfson]

The new order for doubleshot:

1. Expand/alias/flatten
2. Collect each key into its own object and function
3. Fuse
4. Depth-first traversal, calling describe, before, it, etc.
5. Disco.

[twolfson]

To re-iterate, the flattened function, will has the async.forEachSeries logic if it is an array. See renderBatch if you have forgotten what I am talking about.
