ympd on the Raspberry Pi

Due to its small size, ympd is well-suited to run on the Raspberry Pi. Installing it is pretty straightforward:

git clone https://github.com/notandy/ympd.git
cd ympd/
sudo apt-get install cmake libmpdclient-dev
mkdir build
cd build

Install msmtp, a simple sendmail stand-in that sends mail via a relay host (which is what you want, in almost all cases):
```
 brew install msmtp --with-macosx-keyring
```
The flag with-macosx-keyring will make msmtp use the MacOS keychain, which is a pretty secure way to keep your mail account password secure.
Configure it as described in this article. Don't use the manual installation method described there, Homebrew (which we used in step 1) is way more convenient.
Have mail use msmtp instead of sendmail by creating .mailrc with the following content (or adding it, it the file already exists):

	function keychain(){
	# Keychain access idea from https://github.com/defunkt/gist

	if [ "$1" ]; then
	security 2>&1 >/dev/null find-internet-password -gs "$1" \| ruby -e 'puts $1 if STDIN.gets =~ /^password: \"(.*)\"$/'
	else
	echo No argument given. The following passwords are in your chain: >&2
	security dump-keychain \| ruby -e 'ARGF.each_line{\|line\| puts $1 if line =~ /\"srvr\"<blob>=.(.*).$/}'
	fi
	}

	task :import => :environment do
	path = ENV.fetch("CSV_FILE") {
	File.join(File.dirname(__FILE__), *%w[.. .. db data users.csv])
	}

	CSV.foreach(path, headers: true, header_converters: :symbol) do \|row\|
