Support examples and writer variables in the schema parser (#603)

- Added the primitives to 'get_original_blocks'.

- Added test.

Note: get_blocks was not modified - payload body checker support
will need to be addressed separately.  This fix only addresses 'get_original_blocks',
which is used in the main algorithm to generate payloads.

- Fixed compiler inconsistency - handle restler_custom_payload_uuid4_suffix
in the same way as other primitives for quoting.
- Fixed example handling in main algorithm
- fixed several quoting bugs
