[Libreoffice] Installing beta versions replacing stable versions

I downloaded 3.4 Beta 1 and 3.4 Bata 2 under Windows 7, and in both 
cases installing the beta version overwrote the stable version I already 
had installed, and even if I set it to install in a different folder the 
installer still removed the stable version.  Similarly installing the 
DEB packages under Ubuntu removed the previously installed 3.3.2 packages.

Developer versions that are not recommended (and certainly in the case 
of Beta 1 completely unsuitable) for production use overwriting stable 
versions is bad practice for two reasons.  Firstly it makes comparing 
the two versions very slow and difficult if the user has to uninstall 
and reinstall every time they switch between them.  Secondly if the 
experimental version is not suitable for production use then the user 
needs to have a version installed for production use while testing it.

Can you please make sure that future developer builds are compiled to 
install in a separate folder and do not disturb previously installed 
stable versions.

Thanks
