Add word wrap function to WrapLayout and integrate it into TROView

A word wrap function has been added to the WrapLayout class to handle excessively long lines of text. This function has been integrated into the TROView class, ensuring text from various sources (overview, capabilities, deployment, history, manufacturer, factory) doesn't exceed a set limit of 200 characters per line.
