feature: "onView" middleware handler

[jonschlinkert]

Since .onLoad is triggered when a view is "loaded" onto a collection, we don't currently have a catchall middleware handler that would be triggered when a collectionless view is created.

I propose we call this onView, but suggestions are welcome (fwiw, onCreate isn't good since it would cause ambiguity with the .create method)

@jonschlinkert Thanks for the issue! If you're reporting a bug, please be sure to include:

• The version of assemble you are using.
• Your assemblefile.js (This can be in a gist)
• The commandline output. (Screenshot or gist is fine)
• What you expected to happen instead.

If your issue is related to one of the following, please open an issue there:

• grunt-assemble Issues with using assemble in grunt or the grunt-assemble library.
• handlebars-helpers Issues with using handlebars helpers from the handlebars-helpers library.

My $0.02 would be onViewCreate but I like long descriptive naming. ;)

And this would require many changes so probably not a good idea (and my .Net may be showing here), I personally prefer including tense with handlers / events (ie. onLoading, onLoaded, onViewCreating, onViewCreated). Again, just throwing it out there and realize that may be a .Net convention not used in the node world.
