Minor suggestion: File::isAbsolutePath()

Hi, I needed to check whether a path was absolute, and it looks like there is not public method for this. Looking at juce_File.cpp, I found out that this is already done in getChildFile, so what about putting it into a static public method? Here is the patch I propose:
