[aur-general] Christmas cleanup of [community]

[Alexander Rødseth]

Ok, we'll leave lxde, ibus and packages that are dependencies, make
dependencies or optional dependencies for packages in core, extra,
multilib or community, then.
Thanks for pointing this out.

A correction for the historical facts above, btw: Robert Plot was born
in 1640, not 1960, sorry for the confusion (that must surely have
arised :P).

Looking forward to the cleanup.
