[ANN] webgen 1.3.0 - static website generator

[Thomas Leitner]

## About webgen

webgen is a tool to generate static websites by combining content
with template files. You create one or more template files in which
you define the layout of your page and where the content should go.
After that you create page files in which you only define the
content.

You can use a variety of markup languages like Textile or Markdown or
Haml to define your content and you can add dynamic parts via ERB or by
using webgen tags. This allows the automatic generation of menus,
breadcrumb trails and much more!

## webgen 1.3.0

This release fixes some bugs and introduces an updated node finder
filter 'lang'. It now allows to include nodes in the default language
if such a node has no translation to the specified languages. This
means, for example, that if a website is not completely translated to
some language, the untranslated nodes appear in the menu.

### Changes

* 1 minor change:

- [Node finder] filter 'lang' has been updated to support the default
fallback language

* 3 bug fixes:

- Fixed the [website.link_to_current_page] configuration option so
that it really works (reported by Johann Friedrich Heinrichmeyer)
- Virtual nodes now get the correct node class (reported by Johann
Friedrich Heinrichmeyer)
- Fixed [Webgen::PathHandler::Base::Node#url] to always return a
string (reported by Johann Friedrich Heinrichmeyer)

Cheers,
Thomas
