Minor revamp

Remove unused include.
QETproject : Default titleblock are set in the default constructor
instead of set by qetdiagrameditor.
conductor, border, report and xref propertie are now set in the header
of QETProject instead of set by the qetdiagrameditor just after the
creation of a new project.
