core: Fix highlight nick config save/load

Modernize CoreHighlightRuleManager to use the conventions of
DccConfig, saving/loading via SyncableObject serialization handling
for load/save.

This simplifies the code and fixes highlight nick configuration
(highlightNick, nicksCaseSensitive) not being persisted after core
restart.

Add some documentation, too.

Fixes regression from 17c39210b1bce04795046657642de66292518fe6.
