several small fixes

uptracked winboard.ini

Cleanup: moved "Some definitions required..." from winboard.c to config.h,
and combined some definitions from borland w/ MS.

Changed internal HtmlHelp return type and 4th argument to facilitate various
compilers.  These changes, while not strictly adhering to HtmlHelp() conventions,
won't impact anything since the function modified is internal only.

Modified HtmlHelp return values to integer to silence warnings.

Added help.c to the project in makefile.gcc & makefile.ms.

Fixed duplicate resource in winboard.rc.
