git-help: add -w|--web option to display html man page in a browser.
Now when using "git help -w cmd", we will try to show the HTML man
page "git-cmd.html" in your prefered web browser.
To do that "help.c" code will call a new shell script
"git-browse-help".
This currently works only if the HTML versions of the man page
have been installed in $(htmldir) (typically "/usr/share/doc/git-doc"),
so new target to do that is added to "Documentation/Makefile".
The browser to use can be configured using the "web.browser"
config variable.
We try to open a new tab in an existing web browser, if possible.
The code in "git-browse-help" is heavily stolen from "git-mergetool"
by Theodore Y. Ts'o. Thanks.
