Allow for drush --destination while exporting a feature

The drush command also needs the docs updated so that "drush help feature-export" and "drush feature-export --help" display the proper options/docs.

Here's a patch with the following additions/updates to the previous one in this thread.

* Removed extra trailing slash from default destination
* README.txt now documents the new option
* 'drush help fe' now displays the new option and provides some details

I tested and it works as intended, but I did notice a few unhappy side effects:

1. I was able to use '../' as an argument to write the feature outside of Drupal root.
2. Features will let you re-create a module of the same name in a different location without the usual warning of "Module appears to already exist in sites/all/modules/feature_user_perm_view Do you really want to continue? (y/n):"

Anybody think either of those two items are show-stoppers for getting this patch committed?

Here's another try at submitting the previous patch. Last upload failed mysteriously.

Committed to 7.x thanks. http://drupalcode.org/project/features.git/commit/cb51f54

Possible inclusion in 6.x?

don't know if the drush API changed recently but the attached patch is now needed.

and why not even this one so that if you specify a non-existent destination it will be created.

#1363284: Drush --force option is declared wrong fixed it (should have found it).
interest in getting the recursive mkdir commited ?

If you want the recursive mkdir, can you create a new issue and add a patch specifically to do just that?

rebased for D6 (don't forget to fix other drush option too (double-dash): #1363284: Drush --force option is declared wrong )
please review and push.

please note: I fixed a warning by encapsulating $component into an array():
_drush_features_export($stub, array($component));
