regular.mk: drop fuse-exfat

It's a kernel module now.

Suggested-by: glebfm@
desktop.mk: need to be able to resize ntfs

We're better off providing NTFS support so that Windows partitions
can be shrunk at least if one's not going to just blow these away
upon encounter.
regular.mk: pick up regular lists for installers

A lot of packages that should be in the classic installable images
got missed during initial effort; start merging the difference.
desktop.mk: add os-prober to installers

GRUB won't present dualboot systems in boot menu otherwise.
regular.mk: do not duplicate domain-client

There's domain-client pkglist out there, no need to pull
alterator-net-shares (and alterator-auth it requries)
everywhere.
net: brief remark regarding livecd-save-nfs

A bit longer version is: add the script which cares to protect
the interfaces which has been brought up during NFS root bootup
already from being tampered with by NetworkManager so as to avoid
losing network with networked rootfs.

desktop+live: re-added livecd-firefox

This basically reverts commit c18ef37274c858c1632ccf4d7d729b0492874eea
for all practical purposes and restores the problem with chromium livecd
still that's less of a problem compared to regular builds complaining
that firefox is not the default browser when it's the only one anyways.
regular.mk: un-def -> std-def

kernel-image-un-def doesn't contain suitable aufs as of 3.12.3-alt1,
revert to std-def flavour again for the time being.
desktop+regular: added glxgears

Thanks Aleksey Cheusov for proposing this.
x11: added use/x11/e18

The implementation is identical to e17 one.
regular.mk: added regular-e18.iso

Thanks aris@ there are now e18 packages available;
everything is almost the same distribution-wise.
1.1.16-alt1
