eMule 0.50a ڈاؤن لوڈ

- Added preferences.ini-only option "ExtraPreviewWithMenu" (eMule section) which makes eMule put the "Preview with" command into the root context menu rather than into the preview menu (only applies to extended controls with multiple preview programs set)
- Added "Open preferences.ini" button to the extended options. Remember that you have to close eMule _before_ saving any changes if you want to edit any not preferences.ini-only settings
- AICH hashs work properly in all collection types now
