Right-to-left layout issues

Support for right-to-left layout in ImageGlass is decent, but limited.
Some of the layout problems:

• Settings tabs are fine but the content is aligned to the left.
• The context menu and notification text are also aligned to left.
• The Next/Back and Rotate buttons are in the wrong order when language is set to Arabic (the only RTL language supported true to now)
• The layout of windows such as Share in Facebook, input dialogs and confirm dialogs is also from left to right.
• The About window is entirely LTR (also it has some untranslatable text).
• The same with Extension Manager. Also, the text in the bottom buttons is not centered.
• Other minor ones like the dropdown boxes in Open/Convert dialogs (low priority)

Thanks for attention, it would improve very much the experience of users who speak Arabic, Persian, Hebrew, Urdu etc.

Start by inspecting the Settings tabs, context menu, notification text, navigation and Rotate buttons, About window, Extension Manager, and the Share, input, confirm, Open, and Convert dialogs named in the issue. Check their behavior with Arabic enabled and compare alignment, button order, centering, and translatable text. Done means the listed RTL issues are corrected across these windows, with lower-priority dropdowns addressed if scope permits.
