This branch normalizes the charm URLs in bundles for the GUI, which is expecting at least a <schema>:<series>/<name> style URL. Current proof allows bundles with charms specified only by name, so long as they're in the charmstore already.
Caveats: * Currently only works on ingest * May require a GUI branch as well to add -HEAD if no version number (a smart move anyway) depending on API support.
QA: * Run * Enqueue and ingest at least mysql and mediawiki * bin/enqueue --prefix=~bac/charms/bundles * bin/ingest-queued --prefix=~bac/charms/bundles --limit=100 * Get bac's bundle wiki:wiki - the charms should all have a charm: attribute, and the attributes should all be URLs as specified above.
