Exclude form elements from export

[Benjamin-K]

Some form elements should not be included in the storage. Form elements that should not be included as they do not change the entry or contain sensitive data:

• StaticText
• Password / PasswordWithConfirmation
• HiddenField
• Checkbox (sometimes, otherwise check how to set a default value to always have a column for checkbox fields)
• Section
• ...

We could debate if nodeTypesIgnoredInExport should already be applied in the Finisher, so such values are not even saved (certainly intersting for Password fields, if anyone uses this with DatabaseStorage). My implementation in #25 applies this on export.

I think both would be a great improvement. But especially for password fields, not even storing them should be the preferred way. So maybe we can add both options and add a nodeTypesIgnoredFromStorage setting.

I can even think of a third setting for fields that should be optionally included in the export, sth. like optionalNodeTypesInExport (for example HiddenFields sometimes should be included, sometimes not). But this could also be added as a new feature.

Fixed with #25.
