Python syntax issues in SgtLauncher.py

This concerns sgt-launcher version 0.2.5-0ubuntu1 in Ubuntu focal.

I see the following when installing the package:

Setting up sgt-launcher (0.2.5-0ubuntu1) ...
/usr/lib/python3.8/subprocess.py:838: RuntimeWarning: line buffering (buffering=1) isn't supported in binary mode, the default buffer size will be used
  self.stdin = io.open(p2cwrite, 'wb', bufsize)
/usr/lib/python3/dist-packages/sgtlauncher/SgtLauncher.py:232: SyntaxWarning: "is" with a literal. Did you mean "=="?
  if name is "launcher":
/usr/lib/python3/dist-packages/sgtlauncher/SgtLauncher.py:235: SyntaxWarning: "is" with a literal. Did you mean "=="?
  if name is "loading":
/usr/lib/python3/dist-packages/sgtlauncher/SgtLauncher.py:238: SyntaxWarning: "is" with a literal. Did you mean "=="?
  if name is "game":
/usr/lib/python3/dist-packages/sgtlauncher/SgtLauncher.py:250: SyntaxWarning: "is not" with a literal. Did you mean "!="?
  if name is not "launcher" and os.path.isfile(icon_name):
/usr/lib/python3/dist-packages/sgtlauncher/SgtLauncher.py:260: SyntaxWarning: "is" with a literal. Did you mean "=="?
  if name is "game":

The "line buffering" warning is a different issue, but the SyntaxWarning messages indicate problems with at least one of this package's Python scripts.
