Update conversation list interface: Closes #5727
Use Granite's Thin Pane for horizontal panes: Closes #5855
Revert "Fixed #5820 ("Attach a file" should be title case)."

I erroneously made this string change after string freeze.

This reverts commit dceefa30033af4a6f2a9b9f76ee6f5844b4d1ae7.
Fixed #5876 (eliminate "Attach another file").
Composer buttons clean-up: Closes #5810, Closes #5818
No Outbox icon with Adwaita: Closes #5840
Lighten message count: Fixes #5727
Improve application icon: Closes #3705

Also fixes bug in CMakeLists.txt where the new outbox icon had the
wrong file extension.
Outbox postman error "Reply code 220 ... too long": Closes #5823

Smtp.Greeting decode was flawed, causing the client to get out of
sync with the server.  Essentially, the logic to handle line
continuations was being used everywhere *except* for the Greeting,
a problem with Exim servers.  Hat tip to Charles Phillips whose
help made debugging this a snap.
Fixed #5674 (update help documentation for 0.2).
Updated CMake file to reflect recent documentation changes.
Send client domain/address for HELO/EHLO: Closes #5886
Proper IP address formatting in HELO/EHLO

The last commit missed one thing: when sending a bare IP address
as part of HELO/EHLO, SMTP requires the address is surrounded by
square brackets.
Wrong IMAP password in keyring causes crash: Closes #5749, Closes #4720

This may also resolve #5364, but more testing is required.
Updated debian/control for optional Quantal packaging

Per a suggestion from Seb, this adds Messaging Menu as a hard
dependency for Geary, but if the build system doesn't find it, it
will fall back on libindicate.  This means our packaging should
work for both Precise and Quantal.
Toolbar shows "translatable" when welcome dialog is displayed: Closes #5881
Update quoted text styling: Closes #5789

I've modified Daniel Foré's design slightly to make the background
gray of the quoted text slightly more pronounced.  On some monitors
the original color was so difficult to distinguish it looked plain
white.
Fixed #5014 (in composer, message area should follow Subject in tab order).
Clear & show new message notifications according to spec: Closes #5669, Closes #5606

See http://redmine.yorba.org/projects/geary/wiki/StatusAndNotifications
for specification Yorba is following for new message notifications.
Subject not truncated properly in conversation list: Closes #5712

Spurious whitespace is now removed from the Subject: line before
displaying.
