* modest-tny-folder-tree-view.c:
  - make folder names bold and append (<number>) with the number
    of unread messages for the folder, if there are any. Sadly,
    TNY_ACCOUNT_TREE_MODEL_UNREAD_COLUMN never contains anything
    but 0
* modest-tny-header-tree-view.c:
  - make message which don't have the 'SEEN'-flag display in bold.
  - added also the the setting of this flags when you select the
    message, but tinymail does not like that (crash), so that code
    has been disabled
* all:
  - fix the macro-mistake due to spuug
