Please include LyXWinInstaller's toolbar in the official LyX Windows installer

[Andreas Karlsson]

Hi Joost,

I have found the new toolbar buttons used by the LyXWinInstaller 
(http://wiki.lyx.org/LyX/UserInterface#LyXWinInstallerToolbar) very useful. 
Especially the ones for bold font, view PDF and line break are very useful. 
Could you please include these also in the official LyX Windows installer?

If possible I think that the Linux/Unix and Mac versions also should use 
these new toolbar buttons. It makes these functions more easily accessible.

Regards
Andreas
