Easy-RSA: New Windows Start menu item for Easy-RSA Non-Admin mode

[TinCanTech]

Following from #559, I would like to request a new Windows Start Menu Item:

• Name="Start EasyRSA shell (Non-admin)"

This would be a second version of this:

• openvpn-build/windows-msi/msi.wxs

  Lines 1148 to 1156 in c107ffd

  	<Component Id="shortcut.easyrsa.easyrsa_start.bat" Guid="{FE9645C1-6EF1-4046-895A-4ED5C98E2570}">
  	<Shortcut
  	Id="shortcut.easyrsa.easyrsa_start.bat"
  	Name="Start EasyRSA shell"
  	Target="[EASYRSADIR]EasyRSA-Start.bat"
  	WorkingDirectory="EASYRSADIR"/>
  	<RemoveFolder Id="shortcut.easyrsa.easyrsa_start.bat" On="uninstall"/>
  	<RegistryValue Root="HKCU" Key="Software\$(var.PRODUCT_NAME)\Shortcuts" Name="easyrsa.easyrsa_start.bat" Type="integer" Value="1"/>
  	</Component>

The command to be executed is:

• Target="[EASYRSADIR]EasyRSA-Start.bat /NA"

The /NA label is for Non-Admin mode. I am happy to go with any suitable label.

I am not familiar with msi.wxs, which is why this is a feature request and not a PR.

This needs further testing: It may be preferable to use the icon property field "Start in", to set %USERHOMEDRIVE%%USERHOMEPATH%.
