CTextBox: modified AUTO_WIDTH, add some printfs and comments

Browse Source 
If is set m_nMaxWidth, then use this to calculate m_cFrameTextRel.iWidth.
To set m_nMaxWidth use setWindowMaxDimensions(width) and setText(maxwidth).
This should help, to paint text with clean linebreaks
into defined textboxes.
