Proper Serial Console Implementation

[urfdvw]

In Serial Console,
I like the fact that now you can edit the code in a code editor, with new lines and Python highlighting,
before sending it to the console.
This is better than using the CLI interface.

But currently there are too many features missing in the console be cause it is basically just a text display instead of a full console.

The plan is,
Replace the Text out part with Xterm (May come with a default lock),
but keep the python code snippet editor.
