Signing options

There are two possible ways to sign the msi packages:

Copying the file ./PackageData/automation/sign_TEMPLATE.bat into the root of the packaging directory structure, renaming it to sign.bat and changing the contents to your preferred signing options:
- If this is found, ./PackageData/callSignBat.ps1 is used as the interface for calling sign.bat and no further checks for signing options are performed.
After you have set the environment variables PFXFILE and PFXPASS as well as the signtool in the PATH:
- If you want to sign with PFX, you can either add environment variables for PFXFILE and PFXPASS yourself or you can use the ./PackageData/automation/setSignEnvironment_TEMPLATE.ps1, copy it into the root of the packaging directory structure and rename it to setSignEnvironment.ps1. SignTool.exe must be present in the PATH too for that to be considered.
