filezilla: normalise whitespace (was a mix of tabs and spaces)

I don't see these mix of spaces in Atom editor hence why they get submitted. To me everything between <package and </package is in line and indented one tab.

In atom you can go File > Settings > Editor and then not far up from the bottom of the list of options you can "Show invisibles". The defaults look to put a centred dot for a space, and a » for a tab, so in the editor you see e.g.

» » A line with a tab in front of it
····A line with four spaces in front of it

so even though the text "A line with..." lines up vertically you can see the difference in the whitespace before it.

Settings changed in Atom so hopefully my formatting won't annoy you now.
