Dockerfile: git-pull more history, to get a version string

The Docker build process seems to use 'git pull --depth=1', which
doesn't fetch enough history to see a tag, which means tahoe's setup.py
can't compute a version (then 'tahoe --version' reports "unknown").
Pulling a hundred commits should be enough to see a tag without making
the resulting image unnecessarily large. If we go more than 100 commits
between tags, we'll need to increase this, or come up with something
smarter.

Merge branch 'globalopts2'

Improves CLI rendering of --help for global options. Closes ticket:2233.

wrap long lines, and tolerate various-width wrappings of the --help output

test_cli.Help was too sensitive to the way that the --help output was
wrapped, which caused failures on travis when COLUMNS= was set low and
the expected strings were split across separate lines.

cli: improve formatting of all commands

Also:

* do some light refactoring of create-client/node
* make it clear that these commands' --basedir options do the same as
  the global --node-directory option
* use "global-options" instead of "global-opts"

scripts: improve rendering of synopsis/usage

Subcommands "--help" is now rendered as:

```
 tahoe [global-options] COMMAND [options] ARGS
 (use 'tahoe --help' to view global options)
 USAGE (flags/options)
 DESCRIPTION
 DESCRIPTION_UNWRAPPED
```

The new .description and .description_unwrapped fields allow
commands (subclasses of twisted.python.usage.Usage) better control over
how their explanations are rendered: the old .longdesc field was wrapped
unpleasantly.
