Bug 477007 - Do not use white space in XML

Writing and reading XML white space is unnecessary from a programmatic
point of view, and increases the size of compressed and decompressed
files.  Given that the repository sizes can be quite large removing the
white space at creation time will save download and decompression memory

Removing white space from the artifacts.xml file results in around a
10% space saving before compression.
