Enable drag and drop text into termite from another program

[BarbUk]

This is a nice feature.

Drag and droping a file from a file manager produce two issues:

• text if prefixed by file://
• text contain an EOL

A modification to handle drag and drop of file:

static void target_drag_data_received(GtkWidget *,
                GdkDragContext     *,
                gint                ,
                gint                ,
                GtkSelectionData   *data,
                guint               ,
                guint               ,
                            keybind_info vte_info){
    VteTerminal *vte =vte_info.vte;

    std::string selection(reinterpret_cast<const char *>( gtk_selection_data_get_text(data) ));
    std::string needle = "file://";
    if (selection.compare(0, needle.length(), needle) == 0) {
        selection.erase(0, needle.length());
    }

    selection.erase(std::remove(selection.begin(), selection.end(), '\n'), selection.end());
    const char * t = selection.c_str();
    vte_terminal_feed_child (vte, t, -1);
}
