Feature: Pause Autocomplete

[bkyle]

This patch allows the user to pause/resume autocomplete (#13) for the duration of the Visual Studio Code session. The status bar item indicates that autocomplete is paused through the displayed icon as well as the tooltip.

Additional changes

• New: Added command llama.pause, "Llama Coder: Pause" -- pause autocomplete until resumed or the session is restarted.
• New: Added command llama.resume, "Llama Coder: Resume" -- resume autocomplete after being previously paused.
• New: Added command llama.toggle, "Llama Coder: Toggle" -- toggle the paused state of inferencing.
• Change: Modified command llama.openSettings now available in the command palette as "Llama Coder: Open Settings".
• Change: Clicking on the status bar item will invoke llama.toggle instead of llama.openSettings.
