subsurface-startup: expose print_version() in the header

The Windows auto-verbose + log file creation if starting
from a non-terminal has the problem that the print_version()
call is never made becase 'verbose' is updated programatically
in windows.c and not by the user (by passing -v).

To work around the issue:
- move the windows console creation call before *everything* else
- then immediatelly install the message handler
- then see if 'verbose' is set and explicitly call print_version()

print_version() now also has a flag (version_printed), to avoid
printing the version multiple times, if the user decided to add
an extra -v to the Desktop shortcut.
