Add keyboard shortcuts for CodeEditor Widget (danmar#1931)

scottfurry · danmar · commit 6d3d44835ac4 · 2019-06-28T17:17:24.000+02:00
Functionality for `copy` and `select all` text already exists as part
of widget construction. Commit adds connection of those existing
functions to execution with keyboard shortcuts user would normally expect.
(e.g. CTRL+C for copy text)

Qt does translation of keyboard shortcuts for platform
(i.e. Mac OS uses command key rather than control).
