[Build] Larger build system update

FIXED: Core now builds under cmake for Windows

TODO: Map and mmap gen currently does not build

TODO: More sync work is required for Eluna, thus Eluna is temporarily disabled

This has only been tested under Windows with CMAKE and VS

"This script builds the MaNGOS server.
Options that can be used in order to configure the process:
General:
CMAKE_INSTALL_PREFIX Path where the server should be installed to
CMAKE_BUILD_TYPE Sets build type (Release;Debug;...)
CONF_DIR Path to the configs, can be absolute or relative.
PCH Use precompiled headers
INCLUDE_BINDINGS_DIR Include a script library in src/bindings/ with the
defined name. the name must corespond to the name of
the folder and the folder must contain a valid
CMakeLists.txt
DEBUG Debug mode
USE_STD_MALLOC Use standard malloc instead of TBB
ACE_USE_EXTERNAL Use external ACE
BUILD_TOOLS Build map/vmap/mmap extractors
SOAP Enable remote access via SOAP
Scripting engines:
SCRIPT_LIB_ELUNA Compile with support for Eluna scripts
SCRIPT_LIB_SD2 Compile with support for ScriptDev2 scripts
To set an option simply type -D<OPTION>=<VALUE> after 'cmake <srcs>'.
Also, you can specify the generator with -G. see 'cmake --help' for more details
For example: cmake .. -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=/opt/mangos"
For example: cmake .. -DDEBUG=1 -DCMAKE_INSTALL_PREFIX=/opt/mangos"
Note: On UNIX systems, CONF_DIR is relative to the bin folder.
