QC_ApplicationWindow::slotHelpManual

Can we drop support for QT_VERSION < 0x040400 ?

Also, I noticed:

if ((RS_SYSTEM->getDocPath().length()>0) && (QFile::exists(RS_SYSTEM->getDocPath()+ "/LibreCADdoc.qhc")==true)) {
...

        } else {
            QMessageBox::information(this, tr("Help files not found"), tr("Bugger, I couldn't find the helpfiles on the filesystem."));
        }

which is relevant for:
http://forum.librecad.org/Help-error-message-td5712456.html

It looks like LibreCADdoc.qhc either isn't getting created or the function can't find it on that system.

yes, we should drop support for qt before qt-4.4

I feel we should make qt5 mandatory next year

I would support that. I'm interested in an alternative way to save settings using the 5.0+ JSON classes.
