Support Nodejs v5.0.0.0

[david-jointech]

bin/installDeps.sh will fail with nodejs v5.0.0 with following error message.

You're running a wrong version of node, or io.js is not installed. You're using v5.0.0, we need node v0.10.x or higher

I'm trying to run etherpad in an arch-based dockercontainer with following Dockerfile

FROM eorlbruder/supervisord
MAINTAINER David Magnus Henriques <eorlbruder@magnus-henriques.de>

RUN pacman -Syyu --noconfirm --noprogressbar pkg-config git python nodejs npm && \
    pacman -Sc --noconfirm 
RUN mkdir /app 
RUN git clone https://github.com/ether/etherpad-lite.git /app

ADD assets/settings.json /app/settings.json
ADD assets/etherpad.conf /etc/supervisor/conf.d/etherpad.conf

RUN /app/bin/installDeps.sh

Fixed in #2828
