progopedia.com has been launched

[Ivan Levashew]

progopedia.ru is a Russian project (2 years old or more) that collects
PL description, history, information about dialects, implementation
and so on. I have done several contributions to this project.

Now progopedia goes English. My English isn't that good so you're
welcome to fill it's English counterpart and keep it in an actual
state.
