* package/harbour.mft
+ added version manifest to Harbour compiler binaries, which is more
important on Windows 10 builds, to not include false Windows version
in build info.
This doesn't affect programs built with Harbour, where similar manifest
should be included or not, according to your needs.
* utils/hbmk2/hbmk2.prg
* define _UNICODE (activates unicode C RTL functions in OpenWatcom
and some MS C compilers) together with UNICODE in -winuni mode.
Similar change was done in Viktor's forked Harbour 3.4. Harbour
core/contrib code doesn't use any of these C RTL, but in most 3rd
party code it's expected that these are enabled both.
