Support localization

Hi and thanks for this

unfortunatelly I could not apply it

git apply support_languages.patch
support_languages.patch:11: trailing whitespace.
  
support_languages.patch:16: trailing whitespace.
  
warning: 2 lines add whitespace errors.

I'll test and commit it as soon as possible.

No further support for 1.x branch, makes no sense to double work here and 2.x seems to work fine so far.

This is applicable to 7.x-2.x

This is basically same idea as the old 1.x patch.

Looks like this doesn't apply to the latest dev version.

Additionally, language parameter needs to also be passed in this url() call:

$urls = array(url($uri, array('absolute' => TRUE, 'alias' => TRUE)));

This patch also supports https domain statistics.

It still doesn't apply to the latest revision. I think that in latest commit (http://cgit.drupalcode.org/piwik_stats/commit/?id=dd9eb8ef9ab9f8c3c14387...) the sub_url part was mistakenly committed - I am not sure though.
