Summary:                    FindSubversion.cmake macro Subversion_WC_LOG hangs
if credentials are not set.
Description: 
If you call Subversion_WC_LOG on a directory and you do not have credentials to
access the server, the macro will hang while the SVN executable waits for a
password to be supplied

Steps to Reproduce: 
Have a working copy but do not have saved credentials.  Attempt to call
Subversion_WC_LOG with that working copy as the supplied directory.  Observe
that the script hangs.  Hit control-c, which will be passed to the SVN
executable and cause it to break.  Observe that the returned output printed to
the terminal shows the SVN prompt for a password.

Additional Information: 
This is easily handled by passing the argument --non-interactive to the SVN
executable.  I'm including a patch which adds this argument to the call.

NOTE: It may also be possible the Subversion_WC_INFO to suffer this same
problem, though I think that is unlikely.  --non-interactive could be added to
this call as well, possibly abstracting the arguments out into
${Subversion_SVN_EXECUTABLE_DEFAULT_ARGUMENTS} might be appropriate.
