    FindAdv: Added handling for latex environments
    
    1.) Make sure the environment is mentioned in the string for search
      (Added the keyword \latexenvironment{...})
    2.) Handle it similar to \textcolor{}
    
    That way we can also search for 'conclusion*' or 'summary' etc
    in Additional.lyx.
