* dotScene loader now correctly loads materials in <externals> tag. This means models exported in "Separated Materials" mode now work. Also models exported in single material mode no longer require you to rename them to match the scene name. Fixes issue 519. * dotScene loader also considers the ambient color in the <environment> tag and adds an AmbientLight to the scene. git-svn-id: https://jmonkeyengine.googlecode.com/svn/trunk@9736 75d07b2b-3a1a-0410-a2c5-0572b91ccdca3.0
