Mattes D 01b8ed5295
Pulled the BlockID and BlockInfo headers from Globals.h. (#4591) 
The BlockID.h file was removed from Globals.h and renamed to BlockType.h (main change)
The BlockInfo.h file was removed from Globals.h (main change)
The ENUM_BLOCK_ID and ENUM_ITEM_ID enum names were replaced with ENUM_BLOCK_TYPE and ENUM_ITEM_TYPE (cosmetics)
The various enums, such as eDimension, eDamageType and eExplosionSource were moved from BlockType.h to Defines.h, together with the helper functions for converting between them and strings (StringToDimension et al.) (minor)
Many inline functions were moved from headers to their respective cpp files, so that BlockType.h could be included only into the cpp file, rather than the header.
That broke our tests a bit, since they pick bits and pieces out of the main code and provide stubs for the rest; they had to be re-stubbed and re-verified.
eMonsterType values are no longer tied to E_ITEM_SPAWN_EGG_META_* values

// Globals.h
// This file gets included from every module in the project, so that global symbols may be introduced easily
// Also used for precompiled header generation in MSVC environments

// Disable some warnings that we don't care about:
#pragma warning(disable:4100) // Unreferenced formal parameter
// Useful warnings from warning level 4:
#pragma warning(3 : 4189) // Local variable is initialized but not referenced
#pragma warning(3 : 4245) // Conversion from 'type1' to 'type2', signed / unsigned mismatch
#pragma warning(3 : 4310) // Cast truncates constant value

#pragma warning(3 : 4702) // Unreachable code
#pragma warning(3 : 4706) // Assignment within conditional expression
// 2014-10-23 xoft: Disabled this because the new C++11 headers in MSVC produce tons of these warnings uselessly
// #pragma warning(3 : 4127) // Conditional expression is constant
// Disabling this warning, because we know what we're doing when we're doing this:
#pragma warning(disable: 4355) // 'this' used in initializer list
// Disabled because it's useless:
#pragma warning(disable: 4512) // 'class': assignment operator could not be generated - reported for each class that has a reference-type member
#pragma warning(disable: 4351) // new behavior: elements of array 'member' will be default initialized
// 2014_01_06 xoft: Disabled this warning because MSVC is stupid and reports it in obviously wrong places
