SvnClient output encoding

[pvones]

Add input parameter to specify output encoding of SvnClient captured console output, similar to StdOutEncoding of Exec task. Currently it does not return SVN xml log with correct encoding.

Example:

<SvnClient ToolPath="$(SvnToolsPath)" RepositoryPath="$(Path_Repo)" Command="log" Xml="true" Verbose="true">
  <Output TaskParameter="StandardOutput" PropertyName="svnLogContent" />
</SvnClient>
<WriteLinesToFile File="$(SvnLogFileName)" Lines="$(svnLogContent)" Encoding="utf-8" Overwrite="true" />

While using Exec task the xml output have correct encoding:

<Exec Command='"$(SvnToolsPath)\svn.exe" log "$(Path_Repo)" --xml --verbose --non-interactive --no-auth-cache &gt; "$(SvnLogFileName)"' StdOutEncoding="utf-8" />
