[PATCH] fixes for hh.exe

[Gerard Patel <gerard.patel@nerim.net>]

Trying to make hh.exe (html help) just start with a computer with NT 
installed led to a few misc trivial fixes and stubs.

shlwapi.StrRChr : allow both pointers to be null
stubs for CreateAsyncBindCtxEx,  GetUrlCacheEntryInfoA,
CommitUrlCacheEntryA

ChangeLog:

	* dlls/shlwapi/string.c, urlmon/urlmon.c, urlmon.spec, wininet/internet.c,
wininet.spec
               trivial fixes for shlwapi and Internet routines
