Binding Syntax Selector

[brandonseydel]

What

Create an option in the CLI to choose/make a custom syntax

How

We already have ShortHandBindingSyntax (Vue) and hopefully an Angular one in the near future. Would like the CLI to ask if the user would like to add additional binding syntaxes or create a custom one.

Why

Many of the Aurelia gems are hidden and this is something really neat that would show it off.
