Move user information after save/reload to the command level

Moving user information to calcurse.c makes it easier to perform the actual
save/reload operatons in io.c, e.g. it is possible to load instead of
reload after a merge in conflict resolving.

The save/reload operations are of such importance that the user should always be
informed of the result (it's a bit disquieting when there is no reaction to a
save or reload command). Hence, the save/reload status messages are no longer
conditioned by show_dialogs(). No confirmation is asked for, so a message stays
until the status bar is updated by another action.

Care is taken to inform about save/reload actions that result in no change.

Texts are kept concise because of the limited message area. When conflicts are
present, whether saving or reloading, the "continue/merge/cancel" pattern seems
easier to grasp.
