Add --non-interactive to SVN command lines.
Review Request #7308 — Created May 16, 2015 and submitted — Latest diff uploaded
When the username and password are passed in to SVN, it can sometimes prompt
the user for whether or not they want to save the password permanently (and
likely make other prompts). This change adds --non-interactive to all SVN
command lines to make sure that nothing gets blocked waiting for user input.
Ran unit tests.
