Update to 3.17.2

Changelog:

• Message List: A context menu has been added to the column headers, it has two entries: a new option, 'Lock column headers', and 'Set displayed colums'.

• Folder List: A context menu has been added to the column headers, containing 'Set displayed columns'.

• Preferences: The Display/Summaries option page has been split into three notebook pages: Folder List, Message List, and Defaults. The Message List page contains the new 'Lock column headers' option. The Defaults page contains several new options for new folders.

• New Folder Properties: It is now possible to control signing and encrypting options on the Compose page. By default it follows the Account preferences, but they can be overridden to always sign and/or encrypt, or never sign/encrypt.

• Saving sent messages: The global preference, 'Save sent messages', can now be overriden by the Folder Property and Account preferences. The global preference no longer needs to be activated for the Account Preference, 'Put sent messages in ...' option to function. Likewise, the Folder Property, 'Save copy of outgoing messages to this folder instead of Sent', no longer relies on the global preference being set.

• SSL/TLS certificates: The SHA-256 fingerprint is now displayed, and the MD5 fingerprint has been removed.

• SSL/TLS certificates list: Status and Expiry columns have been added, and expired and invalid certificates are now clearly indicated.

• QuickSearch: body searches are now quicker.

• QuickSearch: symbols used in Extended searches are now expanded in the 'Edit' dialogue.

• Re-editing: Flags and tags are now preserved when re-editing a message.

• Fancy plugin: The minimum required webkitgtk version is now 1.10.0.

• PDF Viewer plugin: Ctrl+scroll now zooms.

• Tools: added cm-break.pl script, which breaks thread references for the selected messages; textviewer.pl has been updated and now requires perl 5.14.1.

• The legacy "sylpheed-claws" symlink is no longer installed in the bindir.

• New translation: Portuguese.

• Updated translations: Brazilian Portuguese, Catalan, Czech, Danish, Dutch, French, German, Russian, Slovak, Spanish, Swedish, Turkish.
