Released vibe-core 1.0.0 and vibe.d 0.8.0

[Sönke Ludwig via Digitalmars-d-announce]

Note: Due to recent issues with OpenSSL, the way OpenSSL/Botan get 
selected as the TLS provider has changed. If you are using Botan, you'll 
have to explicitly select the "botan" configuration of the new 
"vibe-d:tls" package:

	dependency "vibe-d:tls" version="~>0.8.0"
	subConfiguration "vibe-d:tls" "botan"

or for dub.json:

	"dependencies": {
		...
		"vibe-d:tls": "~>0.8.0"
	},
	"subConfigurations": {
		...
		"vibe-d:tls": "botan"
	}
