We didn't use interactive service when gui was running
under admin because of some privilege escalation vulnerability in Vista.
Apparently this issue doesn't exist on Win7 and newer versions so
it is safe to use iservice on those systems.
Introduce "Always use interactive service" option,
which is "on" by default. This should enable users,
who by various reasons run gui as admin, use Wintun.
When gui is running as admin and interactive service
cannot be started or not installed, warn that wintun will not work.

When a connection is attempted using a config in a location
that would fail, offer an option to add the user to the "OpenVPN
Administrators" group. This is done using shell-execute which will
show a UAC prompt for elevation. If it fails (due to user chooses
NO or the UAC dialog fails) the connection is not started.
v2 Changes
- Rebase to master
- Automaticlaly add the admin group if it doesn't exist
- Allow unicode strings in debug output
- Use domain\username to identify user
- Fix the PrintDebug macro
Minor changes based on user feedback
- Bring the window back to foreground after UAC prompt completion
- Show a message if another connection is tried during authorization
- Do not add user to ovpn_admin_group if it is same as the built-in admin group
