Simplify home crumb usage + &exclude property + @INLINE support

Simplify home crumb usage. Now, the &showHomeCrumb=1 property adds the
home crumb at the start of breadcrumb and &showHomeCrumb=0 hides it if
present.
Add &exclude property to exlude one or many resources from breadcumb
Tpl @CODE no longer supported. Use @INLINE instead.
&resourceId no longer supported. Use &to property instead
