Provide blocks for Entity Add forms

Hi,

The great thing about ECK is being able to create Entities from within the administrative interface which saves a lot of time and opens up new capabilities to non-coders. Rules and views integration means you can build entire solutions without writing any code.

We wanted to also position a create form for users on the front end of our site, but this required writing a couple of lines of PHP code - which is easy, but still disrupts the idea of doing everything within the admin interface.

So I've created a module called eck_blocks. For each entity type/bundle the module provides a block for the add form for the type/bundle.

This helps a non-coder user by giving them even more abilities (placing create forms anywhere on their site) without having to use code.

It's very small and simple code, and I only created it as a separate module to keep our project clean. So if you find it useful, I think it would be better to integrate the code into the core eck project.

Please see attached the module in a zip.
