port: P3-d PythonTextTail + textTail module (1:1 40250)

Browse Source 
Copy PythonTextTail.cpp/PythonTextTailModule.cpp verbatim, drop the pending
stand-in and the textTail module stub, register initTextTail() after
initChat() and call CPythonTextTail::Initialize() in Create as 40250 does.
Implement CScreen::ProjectPosition/UnprojectPosition (were stubs) with
D3DXVec3Project/Unproject, and ApplicationStringTable_GetString(DWORD) over
UserInterface.rc's English string table. port.login_flow projects the ground
item's name tail in an ALT frame and picks it back by screen position.
