Remove redundant draw call

Fix uninitialized usage of uiWidgetDrawBase

New widget types for drawing scrollbars using widget pipeline

Had to add UI_WTYPE_SCROLL_BACK and UI_WTYPE_SCROLL_INNER since they need different rectangles, drawing and states. Also renamed UI_WTYPE_SCROLL to UI_WTYPE_LISTSCROLL as it's only used for lists.

Cleanup: Naming, comments, redundant defines, ...

Cleanup: Move widget_type function to widgets.c and widget type enum to widget.h

And suddenly, things are soooo much nicer ;)

New widget type for preview menu items

Also to avoid special draw calls.

Note: This adds iconid and str args to uiWidgetDrawType->text callback, which is currently only needed for preview menu items (could also be done differently), but in future this might be handy to get rid of uiBut usage on this level.

Avoid special drawing calls for labels within menus by adding a widget type for them

Aaaand finally: Use new pipeline for text drawing as well

Time to use new pipeline for widget states

Still don't really like having this on low draw level, think a better solution would be to handle this via flags and update widgets based on these flags before drawing, but old logic is pretty confusing and spaghettiish here, so would prefer to rework states from scratch at some point.
