kdelibs4: make it compile and work.

I know, the INSTALL section is a mess. Anyone care to fix CMake so that
it won't be a mess? Or fix KDElibs so that it can use "data" not "share"?
kdelibs4: forgot to uncomment this before commiting.
mpd: Update patchset

Adds an icon and use it for notifications.

Also set buffer size to 4k since 1k seems a bit small here.
Curl 7.37:

* Fix libcurl version.
* Fix ca_root_certificate path. The file can be reached in $dataDir
without problems.
Bump version of ca_root_certificates.

While the recipe is correct, the package uplaoded in the repos is
apparently not built from it, as it contains the source file from
mozilla instead of the converted one in curl format. What happened here?
Add python to curl build_prerequires.

Not used for the build, but used for the tests (of which several are
currently failing).
Revert part of previous curl change.

Olta pointed out that using the package links is indeed the correct way
to handle the absolute location of the ca root certificates, and this
change was not needed for things to work.
fribidi: add recipe for version 0.19.6
