Create or Update the build from the 3.5 branch

Hi all

I'm interested in collaborating with Portableapps to make available a portable version of the last stable version for each branch. These portable versions would be very useful to check for regressions in LibreOffice.

What do I need to do to update 3.5.5 portable to 3.5.7.2 (the latest and possibly last version in the 3.5 branch)?

Cheers,
Pedro
