Use key files for tracking widget states.

Each EShellView now maintains a GKeyFile for recording disposable widget
state such as tree view path expansion, scroll bar positions, combo box
selections, etc.  The EShellView records changes to the key file to
~/.evolution/<shell-backend>/config/state, and automatically restores
the GKeyFile at startup.

Currently only the mailer uses the key file, but it's intended to serve
all shell views.  It replaces the use of Camel "cmeta" files, as well as
"et-expanded-*" and "folder-tree-expand-state.xml" files.

Also, the mailer's folder tree model now includes a column for tracking
which sidebar folders are expanded.  Folder tree widgets appearing in
dialog windows can copy the sidebar's expanded state using
em_folder_tree_clone_expanded().
