Update list about existence of a mass office hours table per country

[lologhi]

Something like:

Country	Online mass hours table	Link
France	Yes!	http://egliseinfo.catholique.fr
Sweden	No	http://www.katolskakyrkan.se/catholic-parishes-in-sweden/mass-times

• fill table
• move table to the Readme
• create tasks of creating a parser per country when it's possible
