vscode 1.28 update fixes

[jBrizzle]

Correcting the terminal toggling behavior after the changes made to the workbench.action.terminal.toggleTerminal command in Visual Studio Code v1.28.

[jBrizzle]

To summarize the issue introduced in v1.28: The toggling behavior of panels (terminal, output, problems, debug console) changed in version 1.28. The old behavior was:

• Panel shows if not visible.
• Panel hides if visible.

The new behavior is:

• Panel shows if not visible.
• Panel hides if having keyboard focus.
• Panel gets focused when visible but not focused.

This bolded portion above is the cause of the issue. Because it will now focus on the terminal if it is not already focused, we are unable to focus on the editor at all. Each attempt just results in the terminal being opened and focused.

Thanks. I'll take a look at this pull request soon and release a new version once I've reviewed it. (not at my desktop atm)

I merged the change in manually and have updated the extension, v1.0.5. Confirmed working in vscode 1.28.1.

Thanks for the help.
