This is a big one...

### Fixed
 - fixed `zoom()` method of runner which was passed a wrong parameter
 - fixed positioning methods of `TSpan` to position them by its bounding box
 - fixed `flip()` method which flips correctly by center by default now and accepts correct arguments
 - fixed a case in `rbox()` where not always all values of the box were updated
 - fixed `getOrigin()` function used by `transform()` so that all origin (#1085) popssibilities specified in the docs are working
 - fixed positioning of text by its baseline when using `amove()`
 - fixed tons of typings in the svg.d.ts file

### Added
 - added second Parameter to `SVG(el, isHTML)` which allows to explicitely create elements in the HTML namespace (#1058)
 - added `unlink()` and `linker()` to hyperlinked elements to remove or access the underling `<a>` element
 - added `wrap()` method to `Dom` which lets you wrap an element by another one
 - added `orient()` method to `Marker`
 - added `options` parameter to `dispatch()` and `fire()` to allow for more special needs
 - added `newLine()` constructor to `Text` to create a tspan marked as new line (#1088)
 - added lots of tests in es6 format
