Improvements to CS Console

* Errors are now logged properly.
* Can now define classes, methods, etc - no longer has to be an expression body.
* Added `StartCoroutine(IEnumerator routine)` helper method to easily run a Coroutine
* Disabling suggestions now properly stops Explorer trying to update suggestion cache instead of just not showing them. In the rare cases that suggestions cause a crash, disabling them will now prevent those crashes.
* Various other misc improvements behind the scenes
