QML Connection doesn't handle whitspaces in signal signatures properly

If you define a Connetion in QML Like:

Connection {
    signal: "some_signal(param_1, param2)"
    ...
}

it will not get connected because of the whitespace behind the comma.

It should be easy to fix. The problem resists in src/declarative/util/qmlconnection.cpp. In the current git version, the following code lines (line 172 - 177) are relevant:

172:    if (lparen >= 0 && d->signal.length() > lparen+2) {
173:        QStringList l = d->signal.mid(lparen+1,d->signal.length()-lparen-2).split(QLatin1Char(','));
174:        foreach (const QString &s, l) {
175:            sigparams.append(s.toUtf8());
176:        }
177:    }

In Line 173 the parameters are splitet along the comma but all whitespaces are preserved.
Changing Line 175 to: sigparams.append(s.trimmed().toUtf8()); will do the trick.
