New REM client: drop the old plugins and hook leftovers, art sources to ART/UI

The native REM client replaces the dacom plugins (rem-essentials, jflp, numeric,
moors, ranks, shipclass, engclass, storyfactions, ...), the FLAR / ReShade /
DLSS renderer hooks and the Lua event scripts of the ClientHook (all empty or
unused); dacom.ini and dacomsrv.ini no longer load them. flserver.exe and
mysqlcppconn.dll belong to the server. The first-person camera zones are
deferred. The ClientHook's pictures move to ART/UI as the sources of the
generators in tools. REM/Audio and REM/Avatars stay.
