Dry run and Python 3.8 upgrade

This version adds a --dry-run command that will print the full command line and then exit. Mostly useful for testing.

This feature is python3.8+ only since shlex.join() was just added in that version.

Feature: Override Username

This release adds a new --override-username parameter that can be used to override the epic username passed to the game. So far this only seems to work with Diabotical.

Launch Parameter Fix

This update makes it possible to add additional arguments to the rktlnch command line, those will be passed on to the game itself.

The Cycle Continues

No also adds launch parameters from manifest that some games require.

Logging improvement release

This is mostly a behind-the-scenes change, but with this the log output will more accurately reflect the time the steps take by flushing incomplete lines and then adding the status, rather than only printing the complete line.

Minor bugfix

• removed redundant quotes
  • This caused some issues in Diabotical

First release

This release was built from latest master. See README for usage.
