docs: This is important: We load stuff as UTF-8.
  
  We are using in the default Apache Commons loading mechanism.
  
  With two little tweaks: 1. We don't accept any delimimter by default 2.
  We are reading in UTF-8
  
  More about that:

  .html#Loading
  
  From the docs: - If the combination from base path and file name is a
  full URL that points to an existing file, this URL will be used to load
  the file. - If the combination from base path and file name is an
  absolute file name and this file exists, it will be loaded. - If the
  combination from base path and file name is a relative file path that
  points to an existing file, this file will be loaded. - If a file with
  the specified name exists in the user's home directory, this file will be
  loaded. - Otherwise the file name is interpreted as a resource name, and
  it is checked whether the data file can be loaded from the classpath.
  
  @param fileOrUrlOrClasspathUrl Location of the file. Can be on file
  system, or on the classpath. Will both work.
  @return A PropertiesConfiguration or null if there were problems getting
  it.
