Disable scroll buffer for "alt" Grid

Browse source 
The scroll history size for the alternative grid (used by fullscreen
apps such as vim and tmux) is now forced to zero. There are two
motivations for this change:

1. According to the literature, the alt screen should not have scroll
   history.
2. Reduce memory consumption by only allocating the single scroll
   history.

In the future, it may be desirable to support a configuration option to
enable a scroll buffer for the alt screen. By launching without this
feature, we can delay a decision about whether to officially support
this or not.
