gui_synclist move global display settings to list struct

Browse source 
its really painful needing to override global settings in order to change
some aspects of lists

this patch moves:

[scrollbar position, cursor type,
talk_menus, keyclick,
wrap around, scroll paginated]

to variables within the synclist, it also makes updating
after settings changes a necessity

I think I have the static synclists in core covered

(I think the one in gui/list-skinned can be left as is)

this patch allows easy modification these flags on the fly
