Replace OHIF study list search interface

The OHIF study search is very limited. It only provides support for a small number of DICOM tags, and doesn't allow for searching across tags. It would be nice if the functionality were refactored to:

• expose a larger number of fields in the patient and study DICOM model of the real world (and which are available in the Orthanc patient/study APIs)
• make it possible to execute a "simple" search that looks across multiple fields
• provide an "advanced" search dialog where complex queries can be built
