Dependencies finally work correctly in perl libraries (they're each compiled

separately now). Added statusbar code to available to perl, it's now
possible to create new statusbar items with perl scripts.

statusbar_items_redraw(char *name) can now be used to easily redraw all
named statusbar items in screen.

Probably several other changes I've already forgotten :)
