Version misreported in 0.8.0

Version 0.8.0-r1 on Gentoo reports it's version as 0.7.3:

It looks like it's getting that from your Cargo.toml, although I can't find documentation mentioning VERSION instead of CARGO_PKG_VERSION.

tuigreet/src/greeter.rs

Line 398 in c955066

println!("tuigreet {} ({})", env!("VERSION"), env!("TARGET"));

tuigreet/Cargo.toml

Line 3 in c955066

version = "0.7.3"

Good catch, it will be fixed in the next version.
