ENH: DICOM browser rework

Huge performance and usability improvement of DICOM browser.

DICOM indexer:
- Implemented background indexing (in worker thread): indexing may take several minutes and it is not desirable to block the entire application for this long time
- Reduced indexing time by a factor of 3x (previously, inefficient database inserts, unnecessary queries, and table view updates slowed down the insertions)
DICOM browser:
- Removed popups from DICOM browser to not interfere with user workflow (questions, status updates, etc. are display in the browser layout)
- Do not block the GUI while importing data sets, provide continuous, detailed update about indexing progress
- Add separate displayed fields preset for DICOM query-retrieve database (this database is built without having access to the files, so less displayed fields can be computed)
- Condensed table headers in horizontal mode (one row can hold all the search/filter fields instead of using one for each)
- Set default sorting of columns (based on last insertion time, study date, and series number)
- Added option to show DICOM metadata (right-click menu)
- Added option to export datasets to file system (right-click menu)
DICOM database:
- Remove orphan empty directories after deleting files from the database
- Emit signals when the database is opened or closed
- Added display option for specifying column that is used for sorting by default
- Improved displayed field update speed by about a factor of 100x (batch execution is very slow on sqlite and individual queries in a transaction should be used instead)
DICOM query/retrieve:
- Fixed crash when query/retrieve was used from Python (where database cannot be passed to the Q/R widget as a shared pointer)
