Remove ugly RTL writing direction hack.

Instead of hard coding the languages to be rendered as RTL make it dependent on
a translation string. Translate the string LTR to RTL to switch to RTL layout.
This is equivalent to the handling done in the i18n example for Qt Jambi and
while not the best solution at least cleaner than hardcoded languages.

Update hebrew translation for this which is currently the only RTL translation.
lupdate all other translations.
