11 new interface languages: Italian, Hindi, Japanese, Polish, Brazilian Portuguese, Traditional Chinese, Indonesian, Vietnamese, Czech, Turkish and Korean (20 languages in total).
Attachment wording is now also detected in these 11 languages, in addition to the existing ones.
Reworded the support/donation text in all languages.

1.2.0 / 1.2.1: The subject line is now checked for attachment keywords too (e.g. an empty body with the subject "Invoice attached"). When you forward a message, you are also warned if fewer files are attached than the original had. New diagnostics log and a small counter on the settings page. "Send anyway" always works. Note: update asks for one new permission, "Read your email messages", used only to count the attachments of the message being forwarded.
1.1.15: Shorter toolbar label. 1.1.14: Fixes a false "missing attachment" warning when files were attached.
