Does not support custom elements

Hey,

I try to type 'ui-segment' + TAB, it does not generate the <ui-segment></ui-segment>. I think you should work like the VS Code, where in HTML editor, any TAB with something before is an element. ;)

According to W3C Web Components specs (http://www.w3.org/TR/2013/WD-components-intro-20130606/#custom-element-section sec 5.1), the name of the custom element must have a hyphen.

any TAB with something before is an element

Based on the above distinction, I think we can scope this case as "TAB with some name containing hyphen before is a (custom) element". This way it will save us from dropping the standard HTML5 elements validation from zencoding.

While we are at it, another improvement can be made in fuzzy search of standard tags. Currently we are checking the discrete names and aliases. For instance, only art and article form <article> tag, but not arti, artic or articl. We should have a least common pattern to identify the standard tag and then if(inputTagName.StartsWith("art", StringComparison.InvariantCultureIgnoreCase)) return new BlockHtmlControl("article");.
