Create separate build file's for each block

[maheshwaghmare]

I think if there is a inbuilt support for making each block build file separately then this will be awesome improvement.

I notice that if we have created 10 blocks and user used only one of them on a single page then loading remaining block assets are unnecessary. But they are loaded because of we have a single build js and CSS file.

If we create lot of blocks then the build file will be more large.

So, I think if there is a way in which we can create a common and block specific build file's.
