[TYPO3-core] RFC: #15812: Add backend maintenance for login news

[Steffen Kamper]

Hi Ingo,

just a comment from reading.

* i would add deprecated to 
$GLOBALS['TYPO3_CONF_VARS']['BE']['loginNews'] if items are in
* rte would be nice, indeed
* instead deleted = 0 we should use t3lib_BEfunc::deleteClause

Later i would like that these news are also visible in the BE, that 
would make them more useful, but this is something for another RFC

all other +1 by reading.
