[FEATURE] Allow config.cache.all = fe_users:current

The existing TypoScript functionality config.cache.all = ... allows a list
of tables and PIDs to take into account other records for the current page
caches.

The cache lifetime of page 42 takes starttime and endtime of news records of
page 15 and addresses of page 16 into account:

config.cache.42 = tt_news:15,tt_address:16

A new functionality used with "current" allows to take records of the current page
into account as well.

config.cache.all = fe_users:current
