Further refactoring: Moving classes to lib/Newsletter/DBObject, adding
autoloader, Converting to DBObject(-Array).
Using new class names now
Changed ot to NewsletterSend to fit with the new class names.
identing mistake
Added check if module exists - without this check I get "invalid table
key" if the module does not exists but the plugin is active.
Changed ot show_preview to ShowPreview (according to the new class
names)
typo
Added autoloader
Removed constant which was nowhere defined.
Removed javascript reloading of the page. In Chrome, the form didn't
submit because of this call and the preview doesn't appear.
Integrated otTarget, which was already used by some templates but not
handled in Admin.php
Changed class names to new Namings.
configgetvar 'multilingual' => own smarty plugin.
&$smarty -> Zikula_View $view
configgetvar defaultlang -> {lang}
usergetlang -> lang
I accidentaly changed 'defaultlang' to 'lang'. I rechanged these to my
new written plugin 'defaultlang'
