Fhir server integration and patient searching/opening

[wmaethner]

• Added configurable FHIR server support
• Can search for patients on that FHIR server by ID or name
• The search displays a list of results which can be selected and opened
• The open patient's info is then displayed
• Updated the UI as well

Fixed that issue @lbergnehr, it passed the Travis build so should be good now.
