Add a helper script for parsing 'svn log' for the

'Relnotes:' tag in case 'yes' is not explicitly
the first string value following the tab.

As it turns out, a number of commits have bypassed
my filters (both email and 'svn log --search'), and
this script returns the results I want when doing
these searches.
