LyX Userguide issues - update

[Uwe St�hr]

Hello LyX-doc team,

I uploaded a better version of my Userguide (named UserguideA4PDF.lyx to 
prevent confusion).
It could be found at
http://fkurth.de/uwest/LyX/userguide/
or
http://wiki.lyx.org/uploads/LyX/UserGuideA4PDF.lyx

I corrected some mistakes I made and added a footnote in chapter 6.2 to 
defuse bug 449.
