- fix w4 warnings

- add convenience macros for config_db(CFG_GET_SYS_VAL)
- VFSUtil::EnumDirEnts now uses flags instead of bool recursive
- UNUSED() for params, UNUSED2 (<- need better name) for variables
- config.h defines must be tested with #if (always defined) -> allows
detecting misspellings thanks to compiler warnings
- replace debug_assert(0) with debug_warn (its sole purpose)
- replace ScriptingHost::ValueToInt et al with ToPrimitive
- use nommgr.h to disable both mmgr and VC debug heap
