Improve loading of kmz file example

Browse Source 
- The href will always start with path as it is sliced starting from 0
  Not sure if it is possible that window locatin does not have a slash
  unless its some about:-page.
- Should be possible to query for the file name directly without regex,
  if the filename contains special regex characters it may behave
  unexpectedly
