Improve i18n/l10n of Piwik

[julen]

While translating Piwik I have encountered some big issues in terms of i18n, so the application isn't localizable 100%.

Here are some of them, but there may be more:

• Widgetize + SiteManager missing big chunks of text (on Javascript tag page etc)

• 'CoreHome_DayFormat' is not used so the day in the front page can't be localized.

• 'General_ColumnNbVisits' is used directly on graphics to display "X Visits". While a language can have a translation for "Visits", the translation for "X Visits" can be quite different and it can even depend on X. That's why there's a thing called 'plural-forms' in gettext-like systems. So please provide a way to localize "%d visits", not just "visits", and it would be great if there's support for plural-forms too.

• 'General_Website' is used as-is to append the name of the website. This may be ok for some languages, but others may want to alter the order to get "%s website".

This probably also applies to more parts of the Piwik's UI.

• Percentages are not localizable.

While most languages use the "100%" form, there are some which use "%100", so percentages must be localizable too.

• Pagination is not localizable.

Users will always see pagination like "1-3 / 11", but that's not accurate for some languages.

Thanks. I'm deferring this one until we've finished moving all the translateable strings into en.php, and the translation team can identify all the strings (use cases) requiring special handling.

Comments:

• Piwik doesn't use the gettext extension -- i.e., it's one less requirement.
• Masculine vs feminine forms has also been raised.
