Fix various deprecation warning (#113)

* .Site.IsServer was deprecated in Hugo v0.120.0, replaced by hugo.IsServer

* .Site.DisqusShortname was deprecated in Hugo v0.120.0, replaced by .Site.Config.Services.Disqus.Shortname

* Use .RenderString instead of markdownify (solves #104)

* The "tweet" shortcode requires two named parameters user and id.

* Replace .Site.BaseURL by absURL (solves #103)
