Implementing export dialog

As our menus are getting many export entries, it is better to create a
single export dialog where user is able to select the export type and
whether to export selected dives or all of them. This should also be
more intuitive than the current way when export from file menu export
all dives and right click menu on divelist exports only selected dives.
