[PATCH] info.c: Make sure we only edit when there is dive selection

[Lubomir I. Ivanov]

From: "Lubomir I. Ivanov" <neolit123 at gmail.com>

1) info.c: always check for "amount_selected > 0" before calling
edit_multi_dive_info().

2) populate_popup_cb() should only add the "Edit" and "Delete"
items if there are dives are selected

3) in info_menu_delete_cb() we clear the selection, therefore
we need to set "amount_selected" to 0.
