perf scripts python: exported-sql-viewer.py: Add 'About' dialog box

2019-05-15T19:36:47+00:00

With support for Python 2 or 3 and PySide 1 or 2 (Qt 4 or 5), it is useful to see what versions are in use. Add an 'About' dialog box that displays Python, PySide, Qt and database server (SQLite or PostgreSQL) version numbers.
