[Vimoutliner] patch: allow progress items with no children

[Scott Scriven]

Hi, here's a small patch to fix something which has been bugging
me.  It allows you to use checkbox items with a percent but no
children.  I often want to do this, and get annoyed when VO
resets all my childless percents back to 0%.

I've never done any vim scripting before, so I apologize if this
is longer than necessary.

As a side note, I was also rather tempted to fix all the
tab-vs-space issues in that file...  It appears that the author
used a tabstop of 3 spaces, but did not consistently use tabs...
or even a consistent indent width.  So, the indentation is all
messed up.
