Add support for line numbers in copy mode. A new copy-mode-line-numbers

Browse Source 
option has the following modes: off, default (tmux's normal line
numbering where 0 is the top visible line), absolute (first line in
history is 1), relative (relative to the cursor) and hybrid (current
line is absolute, others relative). Also adds
copy-mode-line-number-style and copy-mode-current-line-number-style to
set the style of the line numbers. When copy mode is entered with the
mouse, line numbers stay off.
