Add OpenSUSE Tumbleweed install_dependencies.sh script or placeholder

Here are some of the dependencies that I needed to install in order to get the project to compile:

zypper in \
alsa-devel \
assimp-devel \
freeglut-devel \
freeimage-devel \
gcc-c++ \
glew-devel \
gstreamer-devel \
gstreamer-plugins-base-devel \
libglfw-devel \
libpulse-devel \
libsndfile-devel \
libudev-devel \
libXrandr-devel \
openal-soft-devel \
pugixml-devel \
rtaudio-devel \
uriparser-devel \

# Needed to build projectGenerator
binutils-gold \
boost-devel \
libboost_filesystem-devel \
libboost_system-devel \
libXcursor-devel \
libXinerama-devel \
libXi-devel \
libXxf86vm-devel \
poco-devel \

This is probably not a complete list, since I most likely had some of the dependencies installed already, but it's a start. Would a WIP install script (or README) be an acceptable addition to the project, or would you prefer a complete working install script? I can launch a VM and get the full list pretty easily.

Review the proposed install_dependencies.sh script or README addition and the listed zypper packages. Verify the dependencies needed to compile openFrameworks and projectGenerator on OpenSUSE Tumbleweed, then confirm both build successfully with the documented setup.
