+CHANGES IN RELATION TO ORIGINAL PATCH
+    - don't add nested messages into selection on collapse if parent message
+      is in selection
+    - some changes in messages highlighting
+    - re-written all changes in rcube_imap.php
+    - temporary removed threads caching (see TODO)
+    - use depth=0 for roots
+    - thread expand state is not stored anywhere
+    - removed imap_thread_algorithm option, we're using the best algorithm
+      supported by server and implement REFS sorting in Roundcube
+    - use underlined subject for root with unread children (icon is still supported)
+    - on deleting messages the whole list isn't refreshed
+    - added 'expand unread' button
+
+TODO (must have):
+    - threads caching
+    - updating threaded message list on message delete
+    - don't reload messages list on check_recent
+
+TODO (other):
+    - performance: fetching all messages for list in "expand all" state only,
+      if "expand all" is disabled we should fetch only root messages and fetch
+      children on-demand (on expand button click),
+      Notice: this is not so simple, because we need to fetch children
+    	      to set "unread_children", but we can fetch only flags instead of
+    	      all headers for each child
+    - button in #listcontrols to mark all messages in current thread (with selected
+      root or child message),
+    + thread tree icons
+    + thread css: message row height, thread/status icon alignment
+      (change size of all list icons to 14x14)
+    - remove 'indexsort' label from localization files
+
+TODO (by the way):
+    - use jQuery.inArray instead of find_in_array() (common.js)
+    + use only one function (js) to generate messages list
+
+KNOWN ISSUES:
+    - on new message (check_recent) the whole list is reloaded
+    + table header replacement doesn't work on IE
+    - css issues on IE6
+    + css issues on IE7
+
