Issue 141. Added setting 'modelRequireInit'

[gralen]

Set this config setting to true to require an init function in each of
your models. Super helpful for the initial wire-up of your wheels app to
the database.

Interesting change, can you tell me why it is helpful though?
I don't doubt that it is but I need to know why before accepting :)

(Closing until a reply comes in).

I use the 'modelRequireInit' mod mostly when I'm wiring up a new project, to explicitly make sure I've properly named the model cfc, and that it has been loaded by the framework.

If you have a model cfc which is spelled incorrectly, or not loaded for whatever reason, everything in wheels still works, but you go crazy trying to figure out why none of your object validations, or model init functions aren't being called.

In my case, most of the time I need a model cfc for each table anyways; controllers and views are more obvious when missing.

Makes total sense, now that you mention it, it has happened to me too.

We are however using the "master" branch now, so if possible, can you go ahead and submit a pull request on that branch instead?

Thank you.
