References in FnSub are not replace as part of inlining a component

Started some work on this on https://github.com/toshke/cfhighlander/tree/issue-77
Idea is to add 'regex node replacement' to CFN flattening class, and replace any occurrences of
${Resource} or ${Resource.Property} on tree leaves (primitive values in YAML) with
${RenamedResource} and ${RenamedResource.Property} respectively.

Analysing further it looks like there are limitations to inlining and usage of Fn::Sub (below)

Case1:
Component output defined as simple !Ref Resource.Property
Before:

Value: !FnSub '${SubStack.Outputs.OutputName}'

After

Value: !FnSub '${ResourceFromSubstack.Property}'

Case2:

OutputDefined As Complex structure, e.g
!If [Condition, ResourceA, ResourceB]
Before:

Value: !FnSub '${SubStack.Outputs.OutputName}-Bla'

After
