Instead of running everything through the Compiler just to remove whitespace, we provide a build that is a simple concatenation of all scripts in dependency order. This build (ol-debug.js) should never be used in production (the same applies to the old ol-whitespace.js build). Instead, the intention is that it be used to aid in debugging during development.
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.
