Apache connector with CrowdAuthzSVNAccessFile fails with group names containing spaces

Crowd allows groups to have spaces in them.

The parsing parse_svn_authz_file in Atlassian::Crowd doesn't - it only matches entries with the format "$line =~ /^(\S+)\s*=\s*(\S*)\s*$/"

Slackening this regexp to "/^(.+)\s=\s*(\S*)\s*$/" does appear to fix...but might be less tolerant of whitespace
