[blam] Item: Use ElementExtensions to save properties.

[Carlos Martín Nieto <cmartin src gnome org>]

commit 2ae084fce4b27f8028f6cb0b4e3c7f15e916acd2
Author: Carlos Martín Nieto <carlos cmartin tk>

    Item: Use ElementExtensions to save properties.
    
    The constructor reads in these extensions and caches them as variables
    to be read and written in the normal way.
    
    WriteExtensions() must be called in order for the updated values to
    be serialised.
