[#5462] - Attribute size is lost when tag reportFont is automatically converted to a style tag

When I'm opening reports which use the deprecated tag reportFont with iReport 4.1.2 and then save that report in iReport the reportFont-tag is automatically replaced by the style tag.
That's okay but the size-attribute of reportFont is lost in that replacement.

Attribute size of tag reportFont should be converted to attribute fontSize of tag style when a reportFont tag is converted to a style tag.
