The split command allows delta size changes, which triggers a condition
where the split can overflow into the dirlist. Clamp the minimum size of
a split or vsplit to "1" to prevent the view from overflowing, or
completely covering the message list. A split of 0 will still clear the
split.

Prevent panic when split is called but the msgstore is either not
initialized or has no UIDs. This condition could be triggered by calling
:split or :vsplit immediately at startup.
Use the same logic as the :view command, which could operate in a
similar manner.

The [v]split command panics when it is run with no message selected, or
when messages aren't loaded. Check for a valid selected message before
creating a split, and report an error if one isn't selected.

Add :split and :vsplit commands, which split the message list view to
include a message viewer. Each command takes an int, or a delta value
("+1", "-1"). The int value is the resulting size of the message list,
and a new message viewer will be displayed below / to the right of the
message list. This viewer *does not* set seen flags.
