ship only production runtime files

[osher]

This change will reduce your node_modules on-disk footprint by 97%, from 2.3M to 80K.

The reason is that you ship in your package your tests and your test data, and you do have good tests with large test data samples... :P

tests files, dev-config files, docs and fixture data are not meant to be shipped in the package.

Current situation:

$ du -ah node_modules/bintrees
4.0K    node_modules/bintrees/examples/node.js
4.0K    node_modules/bintrees/examples/client.html
12.0K   node_modules/bintrees/examples

after change:

 du -h node_modules/bintrees                                                                                                                     <aws:lwf>
36K     node_modules/bintrees/dist
24K     node_modules/bintrees/lib
80K     node_modules/bintrees

pacakge size reduces as well:

$  ls -lah *.tgz                                                                                                                                       <aws:lwf>

I'm not sure about dist. Most web-apps do their own bundling and compacting...
However, if you chose not to ship dist - you'll be breaking compatibility and should raise a major.
