Improve and/or update ISP names

[anonymous-matomo-user]

Hi,
I'm a french user of Piwik, and I see that some Internet Service Provider names are not really relevant, or up to date : for example, "Wanadoo" is now commonly named "Orange", "Proxad" is better known as "Free", and "Coucou-networks" as "Free Mobile"

I think it would be better if Piwik shows the best-known names of these providers, in order to improve accuracy and user-friendliness of the displayed data.

Note that it is possible that there are other instances that I have not met on my low traffic site. But these are the most common in France, so probably the most "important" for this country.

Maybe a good starting point ?

I've also fixed a missing dash in the regular expression of the Piwik_getHostnameUrl function : univ-metz.fr, for example, is a valid hostname, that can be used in a URL, right ?
