[TYPO3-core] RFC #16215: Allow array as localconf.php configuration values

Good catch!

I must admit I never used the "all configuration" section of the install 
tool while having DBAL active (do not ask why, I guess because I first 
configure my website and then build upon that and as such never have the 
need at a later time to adjust some setting using this section).

1) Is not a new bug as it is as this since the very beginning of DBAL, 
back in the very old days

Seems like this will be a bit trickier to add than I thought...
