o comment blocks filled arrays disappear
o empty array tags disappear
o empty value tags collapse

This only leaves comment blocks in empty tags, which create
whitespace noise, which fucks up the config.xml real bad,
rippling through to the code that deal with is_array, isset
and actual = array() assignments to fix the faulty config.
Will clean this up one by one later.

Yay, thanks, Wallace!

128M has some crash reports attached, but "modern" i386 systems
have more RAM to spare, too.  Also remove two old expansions to
64M, which are now restrictions, because when they were introduced
the memory limit was 32M.  ;)

(mvc) fix for crash report PHP Catchable fatal error:  Argument 2 passed to Phalcon\Validation::add() must implement interface Phalcon\Validation\ValidatorInterface, array given, called in /usr/local/opnsense/mvc/app/controllers/OPNsense/IDS/Api/ServiceController.php on line 135 and defined in /usr/local/opnsense/mvc/app/models/OPNsense/Base/BaseModel.php

Table layout should cope, if it doesn't it sucks and needs
to be fixed.

Faulty logic is faulty.
