Revert "haskell-unlambda: update to version 0.1.3"

This reverts commit b4a3a61285a3b5e75368b7e6dbf44a9c92943d5b.

The unlambda package failed to build after this change, reverting.
Add lambdabot wrapper and mueval wrapper to make lambdabot run out of the box
Rename 'idea_community_1313' attribute to 'idea_community', i.e. drop the
version number so that it's possible to refer to some "default version of the
package" without knowing what version number that actually is.

The same applies to idea_ultimate_1313.
idea: minor cosmetic chance to fix syntax highlighting in Emacs
ListBinarySearch: add package
wmctrl: apply patch from debian to fix listing windows
file-roller: fix icons
Adding retroshare 0.6 (unstable)
linux_*: update, including CVE-2014-4699 (most likely)

CC #3196. No updates yet on 3.2 and 3.12 branches.
