A big bunch of architecture changes (Segs#542)

* A big bunch of architecture changes

Added/Changed:

* Event serialization using cereal
* EventProcessor serialization support skeleton and introduced a thin
EventSrc class
* Ability to single-step event processing
* add thread libraries to required link libraries for all users of ACE
* Remove old gmock from testing builds, update lua-Sol2
* BitStream is now cereal-serializeable, also a small cleanup/split in
serialization helper headers
* Event classes are marked with  helper comments to ease the serializer
generation
* Add event scanning macros to CMake, use template specialization macros
in serializers.
* Timeout events are no longer using pointers as data variables, since
simple int is the payload they need.
* All Events live in SEGSEvents namespace
* Only 'root' events can have `Event` suffix - this is used by `event
gen` to detect events
* Convoluted Event classes with enums converted to stand-alone enums,
normalized names.
* Character helper function to their own file
* Reduced dependencies between game server files and
    mapserver's DataHelpers.h
* added FX behavior and info serialization support
* added particle system load/save functions.
* begin and abort logout are now callable from lua
* Placate grumpy windows, by disentegration ! :)
* MSVC fix, missing <array> include
