Containers++, Win32/64 building++

- Win32/64 & bundle builds & runs
- ozCore
  * container "key" parameters (for contains(), index(), exclude()) are now
    templated to prevent unnecessary construction (e.g. const char* -> String)
  * removed defaulted parameter for add() etc.
  * Hash*: bucket chain ordering is preserved on cloning
  * further de-duplication of code among containers
- scripts
  * build.sh takes optional platform parameter
