Description
-------

When I'm porting Q/KFileDialog thing to KoFileDialogHelper I found there are some design issues so refactored KoFileDialogHelper.

Now it names as KoFileDialog and moved to kowidgets.

Some use cases of file dialog check return value of dialog.exec(), so static methods are abandoned and a getDialog() method is provided to do whatever you want to the QFileDialog object, using static methods also results in parameter list too long.

Some use cases just use name filters instead of mimetype, so filter setter refactored to 3 methods:
setNameFilter(QString), setNameFilters(QStringList), setMimeTypeFilters(QStringList)

Qt 5.2 introduced QFileDialog::setMimeTypeFilters(QStringList) but its not available through static methods, another excuse to abandon static methods.

Added getXXX() methods as convenience for what static methods usually do.

Testing
-------

Works on OSX.

But I remember the reason static methods are used is related to some kfiledialog-related bugs on Windows, please test whether KFileDialog is still used when setting UseNativeDialog=true in kdeglobals on Windows.


Thanks,

Yue Liu
