[GTK] GtkLauncher should support relative file paths

[Martin Robinson]

This is supported for WinLauncher. It makes GtkLauncher much easier to use for debugging failing tests.

Patch with style and memory leak fix

Xan is saying that GtkLauncher should gradually move to WebKit style, so I've redone my patch using WebKit style and with a small memory leak fix.

Maybe use g_file_test if you only create the object to check that the path is valid?

GOwnPtr for fullPath.

You can use GOwnPtr for fileURL, and have only one branch with fileURI ? fileURI : uri

[Xan Lopez]

Eh, ok, you can't use GOwnPtr ok, so disregard that part.

[Xan Lopez]

I meant GOwnPtr here... you can still keep a single branch since it's ok to call g_free with a NULL pointer though.

Thanks for the review! As we discussed recently, GOwnPtr cannot be used in GtkLauncher. I've implemented your other suggestions though.
