Version number not reset when changing repository URL

[GoogleCodeExporter]

What steps will reproduce the problem?

Given the following code:
    $svn = new PL_SvnClient();
    $svn->setAuth($username, $password);
    $svn->setRepository($some_repository);
    $ver = $svn->getVersion();

The version number will always be the same as the version of the phpsvnclient 
repository.

Proposed solution (ALL of these):
1. The default value for the first parameter to the constructor should be null.
2. Set _repVersion and actVersion to null (or 0) when in setRepository()
3. Don't use _repVersion or actVersion directly. Use a wrapper that will 
refresh them if they are not set yet.
