Subject: [PATCH] Add a quick named-session binding and fix theme reload in
 tmux

prefix S now prompts for a name and runs new-session directly, replacing
the `<prefix> :` then `new -s name` command-mode round trip.

Session numbering in choose-tree (prefix s) turned out to be
session_id, an internal per-server counter with no base-index
equivalent, so it can't be made to start at 1 the way windows do;
named sessions plus C-s search in the tree are the workaround.

Also fixed a bug found while testing: `<prefix> r` re-sources the
whole config, and the trailing `source-file ~/.tmux-dark.conf` at the
end always ran, clobbering a light-themed session on every manual
reload. It now checks the invoking client's theme like the
client-attached hook already does.
