#27 dragora-installer: Activate swap automatically (except for exceptional scenarios)

When there is only one swap partition – which is probably the most common case –, formatting and activating it should, IMO, be done in one step, without requiring user intervention.

Currently, you'll have to hit [OK] after the installer has finished running mkswap. But there's really no other choice than either hitting [OK] or aborting the installation at this point. So, this doesn't make all too much sense, does it?

When there are multiple swap partitions, letting the user choose which ones to activate (the default being all, maybe) would make sense, though.

The current installer can already detect multiple swap partitions, if these were previously activated, they are added to the fstab entry, and if not, formatting is possible.

The installer does not deactivate any (partition, in this case) swap, since it does not hurt to have one there. Also because it will try to use it if it is already activated (previously) and manually by the user (before entering the installer) or if it has been formatted and activated during the installation process...

By the way, there is no need in press [OK] anymore. Simply, the progress will be shown...
