Replaced [[!translatable]] directive with po_translatable_pages setting.
Moved istranslatable/istranslation code to helper functions leaving place for
future caching and/or memoization. The PageSpec functions still work.

i.e. clarify that master pages do not have to obey a special naming convention,
so that migration from/to this plugin is smooth

Apache's content negotiation transparently redirects any old URL (page.html) to
the new one, depending on the client preferred language (i.e. a German browser
will be fed with page.html.de). Transition to this naming convention is then
really smooth.
This naming convention allows one to deliberately display the master page, even
if her browser is configured for another language.
