iis: Improves the iis build system

Now checking for common errors while building. Refactoring
on the build scripts, now there is this build_dependencies.bat
script on the iis sub-folder. By calling this script all the
dependencies should be build under the winbuild/.
This commit also removes build scripts that were not needed
anymore.
iis: Removes unnecessary files from winbuild dir

Those .mak files seems to be part of an old build system.
Since the script are now working fine, this commit removes
all those .mac files and also a CMakeList.txt and the
Makefile.win.
iis: Renamves winbuild to dependencies

Since the directory becomes all about dependencies
there is no need to call it winbuild anymore.
iis: Identifies arch before unzip apache

Currently we need the Apache binary which could be used in
32 or 64 bits. This patch makes usage of 'cl' to identify
which architecture is set.
