* apps_evolution_shell.schemas.in.in: added last_version item.
* shell-errors.xml: added upgrade-remove-1-4 and
upgrade-remove-1-4-confirm dialogues.
* e-shell.c (remove_dir): utility to recursively delete a tree of
files and folders.
(e_shell_attempt_upgrade): keep track of the last upgraded
version, if != current version, and < 1.5, and it exists, offer to
remove ~/evolution. Confirm the offer before actually doing it.
* e-shell-window-commands.c: include gnome-about.
(command_help_faq): fix comment structure
* e-shell.c (attempt_upgrade): moved most of this into
e_shell_attempt_upgrade.
(e_shell_attempt_upgrade): moved most of this into
attempt_upgrade, removed rev args. It makes sense, really!
(e_shell_construct): call e_shell_attempt_upgrade instead.
