icon_update_pixmap default moved to bottom

Browse Source 
The default case is moved to the bottom of the switch case.

The default case should be removed, because the icon has always
a right value, because the icon creation always uses a real value:

kix@debian:~/src/wmaker/wmaker-crm/src$ grep wAppIconCreateForDock *c
appicon.c:WAppIcon *wAppIconCreateForDock(WScreen *scr, char *command, char *wm_instance, char *wm_class, int tile)
dock.c:         btn = wAppIconCreateForDock(scr, NULL, "Logo", "WMClip", TILE_CLIP);

***[3]icon.c: icon->tile_type = TILE_NORMAL;

There are only three cases without value (asterisk in the line start) set
as preprocessor variable. (1) and (2) is the same call. These are the three cases:

Case [1]:

-------------8<--------------
WIcon *icon_create_for_dock(WScreen *scr, char *command, char *wm_instance, char *wm_class, int tile)
{
        WIcon *icon;

        icon = icon_create_core(scr, 0, 0);
        icon->tile_type = tile;
-------------8<--------------

Calls to icon_create_for_dock, is only call in appicon.c:

-------------8<--------------
kix@debian:~/src/wmaker/wmaker-crm/src$ grep icon_create_for_dock *c
appicon.c:      aicon->icon = icon_create_for_dock(scr, command, wm_instance, wm_class, tile);
icon.c:WIcon *icon_create_for_dock(WScreen *scr, char *command, char *wm_instance, char *wm_class, int tile)
kix@debian:~/src/wmaker/wmaker-crm/src$
-------------8<--------------

The call:

-------------8<--------------
WAppIcon *wAppIconCreateForDock(WScreen *scr, char *command, char *wm_instance, char *wm_class, int tile)
{
[snip]
        if (strcmp(wm_class, "WMDock") == 0 && wPreferences.flags.clip_merged_in_dock)
                tile = TILE_CLIP;
        aicon->icon = icon_create_for_dock(scr, command, wm_instance, wm_class, tile);
-------------8<--------------

And the calls to wAppIconCreateForDock() are checked before.

The case [2] is just the line:

-------------8<--------------
WAppIcon *wAppIconCreateForDock(WScreen *scr, char *command, char *wm_instance, char *wm_class, int tile)
{
[snip]
        if (strcmp(wm_class, "WMDock") == 0 && wPreferences.flags.clip_merged_in_dock)
***             tile = TILE_CLIP;
        aicon->icon = icon_create_for_dock(scr, command, wm_instance, wm_class, tile);
-------------8<--------------

Then, is sure too.

The case [3] is:

-------------8<--------------
WIcon *icon_create_for_wwindow(WWindow *wwin)
{
[snip]
        icon->tile_type = TILE_NORMAL;
-------------8<--------------

All windows have TILE_NORMAL.

Then, all cases are secure.
