Reset grid when running reset

Browse source 
In the current scrollback PR the `reset` command does not affect the
scrollback history. To make sure the terminal is properly reset, it
should clear the scrollback history.

To make resetting efficient, instead of resetting the history,
the scrollback history is hidden by setting `grid.scroll_limit` to `0`.
This will not clear the history but instead just make it inaccessible,
which should have the same effect.

The visible area is reset by the shell itself, so in combination this
clears the complete terminal grid from a user perspective.

This fixes #1242.
