fix wacom hotplug and all Intuos 5 issues

- drop custom config:
  (please wacom using folks review this part and think
  about how to get it back if its important to you)

- put default config shipping with  xf86_input_wacom
  into /etc/X11/xorg.conf.d/
  which seems to be interpreted again when
  devices are hot plugged

- when starting x11, also provide xinput
  .. you never know when you need it

This fixes all problems I had:
- device only worked when plugged in, then xorg was started
(an alternative quick fix is switching to terminal by ctrl-alt-F1 and back)
- I had to disable some devices, because eg myaint switched input
device many times a sec rendering it unusable otherwise, some of those devices
configured did not work.

Remove tabs
initrd: Add ehci_pci and hid_generic

These are required to get some (all?) USB keyboards to work in recent
kernels.
initrd: Remove serio and atkbd

These modules don't exist as far as I can tell.

symlinked to save space.
filesystems: add priority option for swap devices.

Useful for setting up raid0-like load balancing for swap.
By giving multiple swap devices the same prio.
kde4: use udisks2 for kde versions that support it.

Currently, none do, although kde 4.10 is supposed to be able to use it.
