New standard template file for 1.5.x preview versions
version Freeplane 1.5.x has been created to facilitate a new mind map style developed by Jonas.
Therefore I changed the standard template name from standard.mm to columns.mm . Jonas is going to
create videos explaining the new features and also showing users how to restore their old standard
template in the preferences.
After a while we shall discuss which version should become the standard template for the final version.
