Fix Extract as Include refactoring for layout attributes

This changeset fixes several issues with the Extract As Include
operation:

1) Transfer all the layout_ attributes to the include
   itself. Generally the layout attributes are particular to the
   inclusion context, they are not shared among the different uses of
   the include. For example, in layout1, the include may be in a
   linear layout and have a layout weight, and in another layout the
   included may need relative layout attachments.

2) Generate a new id for the included tag itself

3) For any layout references to the old extracted id, use the include
   tag id instead

4) Generate the new layout in the same folder as the source of the
   extract operation, since it may depend on properties only defined
   there
