 #92 made the class InfoBoxPanel configurable

The appearance of InfoBoxPanel can be changed as needed for the
requirements. WizardInfoBoxPanel implements the neeed changes.
 #92 remove general information from InfoBoxPanel
 #92 added general information to GenericAbstractWizardPanel
 #92 wrap the general information inside HTML
 #92 moved the general information

Removed the general information from the visual panels and added them to
the wizard panel.
 #92 changed font color of WizardInfoBoxPanel
 #92 delay the first appearance of a warning by 500 ms

A small hack is needed to avoid that the warning is
shown to early. After the settings were read, the warning can not be
shown for a half second. This has to be done as the warning will be
shown when the first component, which contains a mandatory value,
receives the focus. Due to the binding on the components the
isValid()-method will be fired.
 #92 show warnings for BasicInformationVisualPanel
 #92 added warnings to panels implementing isValid()

 #92 enable/disable the wizard action

When the wizard is opened the MetaDataWizardAction gets disabled, till
the wizard is closed again.
