Convert tables to markdown and fix bubbles

This converts all the tables to markdown @rachaelshaw.

I made some changes tho.

You were using `integer` on some bubbles but I saw you have `number` which has some css. I changed it to `number` (the other tables were using `number` already).

I changed the examples to what `find.md` does (e.g.).

Also, there is a `default` parameter on the callback. I didn't like it. If we are going to add defaults, I suggest a new column or something like that.

Last, there is a `<a>.create()</a>` which does nothing. Leave it as is because I think there is no `create` doc even (or I didn't find it). When this is fixed, I will put a proper url there.

This also fixes balderdashy/www.sailsjs.org#45
