cli: to specify basedir sometimes requires "-C" option, other times just an argument

[robk]

while you can say "tahoe create-introducer introducer"

it is an error to say "tahoe create-key-generator key-generator" the latter requires the -C flag. a little more consistency would be nice.

This was previously mentioned in #188 (--basedir vs. --node-directory), but it is better to have a separate ticket for this, so this is now the official ticket for this issue.

I will fix this together with #188.

[JeremyVisser]

I was a little confused by the fact that '-C' is sometimes optional. For example, 'tahoe start .' and 'tahoe start -C .' are synonymous.

Best to have complete consistency, IMO.

With the patch attached to #715, "tahoe create-key-generator keygeneratordir" now works.

In [4614/ticket798]:

Basedir/node directory option improvements for ticket798 branch. addresses #188, #706, #715, #772, #890

Applied to trunk in f952532f0822fbe7 54a9ba8232e2b8e9 a7c474a09893b9aa. NEWS changes were in 0ae556c00ac79d4f 2b15f35b867cebbd.

This ended up also allowing tahoe create-key-generator --multiple ..., not because it's especially useful but because it was implied by using the same code for all create-* commands.
