Publish Rev. 1.4.0 (public comment) of SVCM IG

I have discovered a number of changes that enable a much better rendering of the CapabilityStatements

1. don't include a text element, so as to allow IG builder to create narrative
2. don't include publisher, this will come from the IG details
3. don't include contact, this will come from the IG detail
4. don't include copyright, this will come from the IG detail
5. don't include a version, this will come from the IG detail
6. don't include a publisher, this will come from the IG detail
7. set status to active
8. set experimental to false
9. description is markdown, so leverage markdown for things like links
10. do not put an empty implementationGuide element
11. fhirVersion should be 4.0.1 (later, hope this comes from the IG detail)

The sections ITI 95, 96 and 100 on searching mentions composite search parameters and it isn't relevant. This should be removed.

Should SVCM derive profiles from the sharable profiles defined in FHIR R4 core?

• http://hl7.org/fhir/shareablevalueset.html

Note that R5 has more to choose from... the IG Builder enforces these upon IG authored content.
