Build fails. Possible due to conflicting version of syntex_syntax.

Hi!
After reading #37 I decided to go with a source build of spotifyd on my Raspi 2. Unfortunately the build fails. Probably because two versions of syntex_syntax are getting installed. At least racer-rust/racer#388 and XAMPPRocky/tokei#42 suggest this.

$ cargo build —release
...
Downloading syntex_syntax v0.50.0
Downloading syntex_syntax v0.52.0
Downloading syntex_syntax v0.54.0
...
Compiling syntex_syntax v0.50.0
Compiling syntex_syntax v0.52.0
...
error: Could not compile `syntex_syntax`.

$ uname -a
Linux raspberrypi 4.4.13-v7+ #894 SMP Mon Jun 13 13:13:27 BST 2016 armv7l GNU/Linux

$ rustc -V
rustc 1.16.0 (30cf806ef 2017-03-10)

For completeness: there are more dependencies that get installed in multiple versions, but there hasn’t been an error compiling those (yet):

I'll look into this sometime. I have to bring the librespot dependency up to date anyway, so it'll come up then I guess.

However, as you can see in my last comment in #37, the automated builds should be fixed by now. Please try it out if you haven't already :)

Latest commit should build. It works on my machine and on travis. Feel free to reopen if you still have issues!
