v1.10.0 - signed binaries (#39)

* Sign release binaries with Certum and bump to v2.0.0.0

Add Certum SimplySign cloud code signing to the CD pipeline so gMod.dll
and TpfConvert.exe are signed before being published as release assets.
The signing scripts are ported from gwlauncher (commit 5ae825a).

Signing is gated on the CERTUM_OTP_URI secret, so forks/unconfigured
repos still build, just unsigned. Requires repo secrets CERTUM_OTP_URI,
CERTUM_USERID and CERTUM_CERT_SHA1.

Bump the major version to 2.0.0.0.
