Avoid heap memory allocation and a level of indirection. This allows the compiler to optimize the program even more. No logic has been changed in this patch.
The KeyValues class belongs here. Also reimplemented most loading methods for KeyValues, and adjusted the VPK building code to account for it. Pointers to the engine's implementation of KeyValues have been moved to a separate header ('keyvalues_iface.h'), as this allows external tools code to utilize the standalone KeyValues class implementation. Playlist utilities are completely separated from the KeyValues header; these have nothing to do with KeyValues other than manipulating a global KeyValues object for the playlists, and thus have been named as such and moved to rtech/playlists.

They were all strings; changed them to what made most sense for each field type. Changes:
"hidden": string -> bool
"port": string -> int
"checksum": string -> uint
"playerCount": string -> int
"maxPlayers": string -> int
