Provide disambiguated name in all/most cases

[AMDmi3]

Currently it's common to set a disambiguated name for a less wide spread project, and leave wider spread project with a short name. It seems useful though to set disambiguated names in all cases.

We need to go further and introduce a strong policy of disallowing any packages to be left under ambiguous project names. Benefits:

• Anyone who runs into ambiguous name would always see a sane disambiguation page instead of (one of projects under the given name) or (pile of leftover packages which cannot be cleanly disambiguated)
• It's no longer possible for a newly added package to fall into the wrong project (because of lacking disambiguation rule or homepage information)
• It's easier to look for projects lacking disambiguation on the site. There's no longer need to look for warnings on console, even without introducing problems kind for these cases
• Repositories are encouraged to share more information on packages to classify them properly

The way to do it would be to convert warning: "please classify me" rules into addflag rules and an extra rule which processes packages with set unclassified flag, by adding -unclassified suffix (in addition to generating the warning which may stll be useful).
