Please write blog posts, create tutorials, or develop workshops that show off cool ways to develop applications that use OL3. The examples should be kept very simple. This download functionality is neat, but it's really a gratuitous use of non-map related functionality. While it does demonstrate the use of `format.writeFeatures()`, this is buried in too much additional code that is not accessible (buried in resources/common.js) and not really related to mapping things. If we want to have examples that demonstrate how formats can be used to serialize features, a simple textarea would suffice as the target.
This reverts 4d619d71b1 (see #1527), going back to what we had after e13075f6ff (see #881).
To avoid the 404 in the hosted examples, the css is copied to the same relative path when hosted as during development.
This commit also removes the click listener, which was used for touch devices. The click listener will be added back when the lib will correctly handle clicks on touch devices.
