Issue #433: Fix all localization issues

* enable PDE compiler check for missing localizations in all projects
* unify PDE project settings for all plugin projects
* fix missing tooltip
* localize all remaining non-localized strings in plugin.xml
* set translatable property in all own schemas where applicable
* move all localization files to the default OSGi localization property
location and remove the superfluous manifest headers
