Clark Boylan 7f35178617 Fix package and image list comment cleanup
When cleaning up comments from lines of the form:

  foo bar # this is a comment

You want to remove remove everything after the first comment character
not after the last comment character. This is because:

  foo bar # this is # a comment

Should get everything after bar removed not everything after is.
Unfortunately when you use str.rfind() you remove everything after is
not everything after bar. Switch to regular trusty find to fix this.
