[FEATURE] Automatically determine page type for URIs with format

When rendering a special format a custom page type is required.
This adds a mapping configuration to define which page type
should be used for which format.

Example:
plugin.tx_myext {
    view.formatToPageTypeMapping {
        txt = 99
        pdf = 123
    }
}

The formats defined will apply to all Plugins in your extension.

[BUGFIX] CSS: Default vertical spacing for blocks

Forms, tables, texts need a clear structure and obvious
visual distinction. Our Backend currently does not
deliver strong defaults for extensions.

Many modules already work around this lack of structure
by adding extra spacing and horizontal rules:

- DocumentTemplate::spacer(x-Pixel)
- DocumentTemplate::divider()

This patch brings vertical spacing based on CSS for:

- p
- ul / ol
- dl
- blockquote
