- Download metadata before reading config
- Provide fake config when no config available yet, so user in first run steps is able to choose which step to run first: --install-distro-packages or --generate-config
- Mark incorrect case that I found when the last-metadata-update is not changed in normal use as todo
- Fix endRE, so the "end" word may have spaces before it.
- metadata-only option moved to context options
- Remove mentioning of KDE 4 in the message when no config found

In _downloadKDEProjectMetadata:
- Reorganize variables
- Always create a metadata source dir, even in pretending
- Only allow to skip metadata update when it is already downloaded and user did not specifically ask to not update it with --no-metadata or when skipped update phase. Also fix incorrect condition when update was performed only when update desired (disregarding if it was still needed).
