[PATCH] gitk: make autoselect optional

[Jeff King <peff@peff.net>]

Whenever a commit is selected in the graph pane, its SHA1
is automatically put into the selection buffer for cut and
paste. However, some users may find this behavior annoying
since it can overwrite something they actually wanted to
keep in the buffer.

This patch makes the behavior optional under the name
"Auto-select SHA1", but continues to default to "on".

Here it is, with both requested items and a slightly more coherent
commit message.

Heh. My biggest concern was "did I get everywhere that options must be
mentioned" (which isn't a Tcl thing at all, of course). I tested that
the option works, and that it correctly saves the value in the .gitk
file and respects it on the next run.
