arpi 725ff339e7 This patch adds support for vertical subtitle alignment 
control. Possible values are top, center, and bottom,
with bottom being the default. Alignment is relevant when
it comes to positioning subtitles with one line (or fewer
lines) of text relative to multi-line subtitles.

It is implemented as a new command (sub_alignment) that
without an argument cycles the alignment (between top,
center, and bottom), or with an argument sets the
alignment (0 for top, 1 for center, 2 for bottom).
The key 'i' is bound to this command.
