See: https://discourse.ros.org/t/rosrun-cant-find-osrf-gear-on-kinetic-ubuntu-16-04/1026/4

Using the install space resolved the issue.

Resolves #14 : Fixing devel space builds

Prior to this commit, paths were mostly hard-coded to install space. This eliminates that requirement by using the rospkg python pkg and rospack find shell command to automatically find the correct paths whether the users is building a devel or install space build.

Additionally, the setup.sh script needed a chmod to become executable (and therefore detectable by rosrun).
