Export the number of plural forms as specified in the imported PO file's header

[David Planella]

This is a follow up to bug 565294:

In order to fix the Lithuanian plurals bug we need to export the plurals as they are defined in the imported PO file's header. I'm assuming if they are not defined, the fallback should be the plural definition for the language in Launchpad.

Hebrew has a similar problem, only specific templates should include a different Plural Forms formula

I've just tested and this bug still appears in Natty.

Status changed to 'Confirmed' because the bug affects multiple users.

Rosetta has hardcoded plural forms for each language. If they are differ from Rosetta settings (like in Ukrainian KDE translation) the extra plural form just ignored.

New Transifex (after 1.0) behaves the same way. It seems that soon the developers of online translation tools will dictate translators how to translate... :(

I've changed the order of plural forms in Lithuanian language in KDE. This makes Lithuanian language much less affected by this bug. New .po files will be released with KDE 4.8, so hopefully Lithuanian translation will be in a better state in 12.04 LTS.

I believe this to be a dupe of bug 228719 - we export a plural form definition, but then simply skip forms that are not in LP's database of translations. I'm marking it a dupe accordingly.
