folderman: make escapeAlias public as its now used in accountmigrator.
cfg migration: Add a account migrator class.

Account: Add a wasMigrated flag.

If an account in a branded client was migrated from a former ownCloud

and the account indicates that it was migrated. In that case,

If there is not yet a config for a branded client, but one for the
"normal" client targetting the same URL, it will be migrated.

As requested by Danimos review.
AccountMigrator: Read path from QDir::fromNativeSeperators(), add debug.
