Title: Update compile/inc/Incremental.scala: File.getCanonicalPath instead of java.io.File.equals()

Fix for http://stackoverflow.com/questions/12972183/sbt-always-does-full-rebuild-because-of-modified-binary-dependency-rt-jar
def externalBinaryModified uses java.io.File.equals() to check if files are the same. It's better to use File.getCanonicalPath in this case.
