[Lazarus] AutoCommit

[Ondrej Pokorny]

Usually we try to use the "default" feature of the newly added 
properties so that they are streamed only when really set and used. When 
they are not used, the LFM can still be loaded in a legacy version of 
Lazarus because the new properties are not streamed.
