To components. Because tab-completion works better when there aren't two
things starting with bower, and shorter names are nicer to deal with in
general.
Set up grunt with tasks for:
* preen - deletes unused files from bower_components, configured in
bower.json
* concat - concatenates preened bower components, configured
automagically from the preen config
It's worth noting that this setup assumes the order of files within a
package doesn't matter. This is usually true since we often include only
one file from the package.
Moved all test code into /test. Renamed test.js to crypto_test.js.
(Let's try to keep test files topical.) Merged test_views.html and
test.html into a single test/index.html.
Todo: use Grunt to generate test/index.html from index.html and files
found in /test. Also, write more tests.
