Subject: [PATCH] WPrefs: Avoid crash when config file does not contain
 wmdrawer settings

When first using the wmdrawer panel of WPrefs the settings

ClipAutoexpandDelay
ClipAutocollapseDelay
ClipAutoraiseDelay
ClipAutolowerDelay

are not yet saved in the user's config file and 'value' ends up
being undefined in showData() leading to a crash in adjustButtonSelectionBasedOnValue().

This patch is a workaround to make it possible to choose the config values for the
first time using WPrefs.
