Support for custom templates

[Ben Smith]

Would love to see support for User templates. I find myself making the same changes to each newly created addon to jive with my coding style, purely from a code formatting standpoint.

For example, I always remove the commented "lines":

// --------------------------------------------------------------------

Awesome package Luke!

@benjamin-smith you can now add the "package_custom_template_path" option to your user settings file to set a custom path to your templates.
