Nelsie

New features

* Hierarchical steps (e.g. step 1.2.3 is allowed)
* `initial_counter_value` added into `ListBox`

Changes

* Semantics of steps are now different, but it should be backward compatible with reasonable use cases.
The only real breaking change is removal of `.set_n_steps` and `.get_n_steps`. They have to be replaced by
`.insert_step`, `.remove_step`, and `.get_steps`.

* No actual changes, created to fix incomplete deployment to PyPI

New features

* Clickable links in PDF output
* Font decorations: underline, overline, line-through
* Watching a slide file and automatic rebuild via `python3 -m nelsie watch SLIDES.PY`

Removed features

* GIF support was officially removed, as it was not working in the new renderer released in 0.8

Fixes

* Fixed problem when ListBuilder is used together with steps
* Fixed loading SVG files with DTD

New features

* New PDF renderer. Nelsie now produce smaller slides faster when raster images are used
* Rendering slides & image preprocessing in parallel

Fixes

New features
