[FEATURE] Add TypoScript option to create absolute links and resource/image URLs

A new TypoScript option config.forceAbsoluteUrls = 1
is added, which allows to create ANY link to be absolute (pages
+ files etc), as well as all images, included assets
to have a full qualified domain name.

Setting this option will override any option in
config.absRefPrefix and any typolink.forceAbsoluteUrl = 0
options.

The main benefit is to create a fully static version of
the frontend. Ideally, config.absRefPrefix can then be phased
out and the config.absRefPrefix option
should be removed in favor of this new feature at a later stage.
