RevAger 1.2 should be able to detect pre-1.2 settings automatically

[Daniel Kulesz]

Excerpt from the 1.2rc release notes (https://launchpad.net/revager/+announcement/4561):

* Standard directory name changed from "revager-data" to ".revager". So if you want to keep your settings, you have to rename the directory "revager-data" to ".revager" in your user home directory.

Actually, I think RevAger 1.2+ should search on startup for RevAger 1.1- settings directories automatically and ask the user, whether it should rename it in order to use the old settings. This search should be done only once, so in case the user denies, both "revager-data" and ".revager" directories could peacefully co-exist - just in case, someone wants to keep both versions. I think a condition like ".revager does not exist AND revager-data exists" should do the trick here.

Good idea! I think we should implement this little feature in version 1.2.1. But do we really need a spec-blueprint for this one? ;-)

For me it's rather a bug than a new feature - that's why I removed the feature tags before. Such compatibility problems, where you have to manually migrate settings should not happen in a minor release series, that is in the RevAger 1.x series.
