PG-900 The constructor saved m_defaultBlocksViewerText after it had already been changed when initializing m_blocksViewer.Text when initially in 'rainbow' mode. Moved the initialization of m_defaultBlocksViewerText to HandleStringsLocalized().  m_blocksViewer.Text is still not localized, but couldn't get it to work.  "Who speaks this part?" doesn't localize.

It now initilizes correctly for both "Who speaks this part?" and "Match Reference Text" modes.
