Add updating of data for manga

The title and total numbers can now be changed.

* src/data.c (data_add_manga): Change `name' to `const gchar*', we're
  not changing it.
  (data_update_manga): New function, updates a manga's information.

* src/eom-detail-window.c (eom_detail_window_load): New function,
  prepares the tables to show the right data.
  (add_menu): New function, adds a menu to the window.
  (eom_detail_window_init): Call `add_menu' and prepare the other
  widgets for showing.
  (on_edit): New function, opens an edit dialog and reloads the screen
  afterwards.
  (set_manga_id): Move data filling to `eom_detail_window_load' and
  widget preparation to `eom_detail_window_init' and call
  `eom_detail_window_load'.

* src/eom-detail-window.h (EomDetailWindow): Add `ctable' and `rtable'
  members, these are the tables that show the data.

* src/eom-main-window.c (on_new): No need to save and copy the name of
  a manga, just destroy the widget later and destroy it always.

* src/eom-new-item-dialog.c (eom_new_item_dialog_class_init): Add
  write-only `manga-id' property.
  (EOM_NEW_PROP_MID): New enum.

  get for now.
  (set_manga_id): New function.  Show a manga's information in the
  entries.
  (set_property): New function.  Set a property.  Calls `set_manga_id'
  for the `manga-id' property.

  member.
