[Libreoffice-ux-advise] Reworded msi installer Typical/Custom texts

[Stephan Bergmann]

With 
<http://cgit.freedesktop.org/libreoffice/core/commit/?id=d35849b6f718990869b01209865bb70cb7343ceb> 
"fdo#57927: Clarify msi installer only installs subset of dicts by 
default" for <https://bugs.freedesktop.org/show_bug.cgi?id=57927> "Only 
the dictionary of my mother tongue was installed" (also cherry-picked 
into libreoffice-4-0 and libreoffice-3-6 towards LO 3.6.5), the texts 
that explain Typical vs. Custom installation in the Windows msi 
installer got reworded to match reality, but the wording is somewhat 
awkward, so please feel free to improve it.

Also, <http://www.libreoffice.org/get-help/installation/windows/> 
"Installation of LibreOffice on Windows" contains screenshots from LO 
3.5 that are thus outdated now.
