Fixed bugs with MultiDialog. Fixed Bug with prompting about modules.

Previously MultiDialog attempted to centre on parent dialog, but there was a NULL parent.  Now the application top window is used. Dialog shows centred, for example when there are missing block files.  If the top window is a WX_STAY_ON_TOP, we move our dialog to the left, as otherwise it would be partially hidden.

Previously Audacity would ask about enabling a module whilst the splash screen was showing.  For some as yet undetermined reason the MultiDialog and Splash Screen are incompatible.  Possibly it's related to doing a ShowModal before a full application exists.  The not ideal workaround is to now delay showing the splash screen until after the modules have been loaded.
