#226 Eliminate system DLL wrappers

[Vidar Hasfjord]

The wrappers defined in "module.h" for delay-loading system DLLs — TUser, TVersion, TOle and TOleAuto — are superfluous, since we can just link with the corresponding import library (which for most of the wrapped DLLs is done by default anyway).

[Vidar Hasfjord]

The mentioned wrappers have been eliminated in Owlet [r6393].

More wrappers (TSHReg and TSHPath for "shlwapi.dll") were removed in [r6398], along with the associated files "shelwapi.*". And TThemeModule, the wrapper for "UxTheme.dll", was removed in [r6399],
