Add non-static QProcess::startDetached

The three static QProcess::startDetached overloads support a limited number of
features: program, arguments and working directory. To support more features of
QProcess (without adding a plethora of overloads) we add a non-static method
startDetached that can be used as follows:

QProcess p;
p.setProgram("cat");
p.setArguments("meow");
p.setWorkingDirectory("/tmp");
if (!p.startDetached())
    qWarning("Cannot start process.");

We plan to add support for nativeArguments, processEnvironment,
standard{Output|Error}File and maybe more in subsequent commits.

[ChangeLog][QtCore][QProcess] Added non-static QProcess::startDetached
to support more features for detached processes.
