rJava: adding missing dependencies and JAVA-env-variables
nixos: Add option services.cron.cronFiles

This allows you to configure extra files that should be appended to your
crontab. Implemented by writing to /etc/crontab when the cron service starts.
Would be nicer to use a cron that supports /etc/cron.d but that would require
us to patch vixie-cron.
r-XML: adding system-dependency libxml2
youcompleteme (vim plugin): update to latest

patchShebangs fixes build failure in chroot (in this new version).

The --system-libclang flag is now needed to prevent YouCompleteMe from
trying to download and build clang (which fails).
youcompleteme (vim plugin): use commit date as version number

Using a git commit id as version number doesn't work well, so use the
commit date instead.

Also, there is no other version of YouCompleteMe than the git version,
so drop 'git' from the package name.
Update dolphinEmuMaster

The plan at this point is to update dolphinEmuMaster every month in
tanden with the latest development report on the dolphin-emu.org blog.

I successfully built all reverse dependencies, using this procedure[1]:

  $ nix-env -f . -qaP \* --drv-path | sort > l1
  (...modify package...)
  $ nix-env -f . -qaP \* --drv-path | sort > l2
  $ changed=$(diff l1 l2 | awk '{print $2}' | sort | uniq)
  $ nix-build $(for i in $changed; do echo -A $i; done)
