Add web/drush.wrapper scaffold file for restricting commands/aliases/config to local repo.

[weitzman]

Drush has support for a drush.wrapper in Drupal root which customizes how Drush gets called. The wrapper I propose here adds --local to all Drush requests. This tells Drush not to scan for config, site aliases, and commandfiles in global locations (e.g. ~/.drush, /etc/drush, ...). This environment isolation is very helpful - all Drush requests run the same no matter who's system you are on. Furthermore, it emphasizes that Drush files go in this repo's /drush dir, not in legacy places like ~/.drush. In the rare cases when globally installed commands are needed and can't be copied to our /drush for some reason, user can add --no-local to her request (or in the extreme permanently remove --local from this file).

In order to test this PR, make sure you have some commandfiles, config, or aliases installed to ~/.drush. Then run a drush sa --root=/path/to/web. Notice how your global commands/aliases/config are no longer in effect with this PR.

I've started to use this feature, and think it still needs a little smoothing out, per drush-ops/drush#2023. Some easy option to add on the commandline to negate the use of the drush wrapper (opposite effect as --local) would also be good.

That said, there will be a drush.wrapper equivalent to this one in the Pantheon version of this project.

drush-ops/drush#2023 is still open. I think we should adopt the script without the --local flag. This solves the main use case and we don't have to cd back and forth between project root and web.

[weitzman]

I'm fine with committing this without --local. I wrote above about the value of this option. I will say that clients who really want to bring in drush commands/config from outside the project can still use drush's --config and --alias-path.

[weitzman]

I removed --local. I think this is ready. webflo proposed something similar in #202 (either script would be fine with me).

[weitzman]

Actually, this should go into project root not /web. Lets close this in favor of #202 (or ask people to use drupal-shim project).

@weitzman Just curious : what is the "drupal-shim project" ?

[weitzman]

Sorry, I mistyped. Here it is: drush-shim

[yched]

Ah, right :-)
