run.sh does not correctly handle pathnames containing " " characters

If somewhere in the full path for the location where you are trying to run your controller, you have a path segment with a space, for example:

/tmp/Development Stuff/distribution.opendaylight-0.1.0-SNAPSHOT-osgipackage/opendaylight

(note the " " in "Development Stuff" above)

When you try to execute run.sh, it will fail with the message:

usage: dirname path
Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/equinox/launcher/Main
Caused by: java.lang.ClassNotFoundException: org.eclipse.equinox.launcher.Main

at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
at java.lang.ClassLoader.loadClass(ClassLoader.java:247)

This failure is occurring due to mishandling of the space in "Development Stuff"

Still working on fixing... but wanted folks to know ASAP that the workaround is
to simply do something like

mv /tmp/Development\ Stuff/ /tmp/DevelopmentStuff

in other words, kill the space in the path segment.
