a=brendan r=edburns, scc This checkin does three things: 1. Makes it so on Unix the user can set the env var NS600_PLUGIN_PATH to point to a directory that will be used as the location for searching for plugins. 2. Removes nsPluginsDirUNIX.cpp and replaces it with nsPluginsDirUnix.cpp 3. Correctly formats nsPluginsDirUnix per brendan's recommendation. git-svn-id: svn://10.0.0.236/trunk@80956 18797224-902f-48f8-a5cc-f745e15eee43
