Patch: Add bundle locate (was locate and open commands)

[tomafro]

I've added locate and open commands to bundler: http://github.com/tomafro/bundler/commit/1257532953cbf94eaf4e2737b1f5f19c37118818

If these was any way they could be added to the main project, I'd appreciate it. bundle open, in particular, is invaluable for people like me who like to read the code of the gems they're using.

One of the benefits of 'vendor everything' was the ease which we could trace the implementation of anything our applications used; because bundler usage often means not having the source directly in the application, commands like these are incredibly useful. Please merge it, Carlhuda!

I like locate_gem, but I'm kind of iffy on open. Maybe they could be split into two patches?

Gah! I didn't realise my replies to bryanl didn't get reflected here. I've supplied a patch for just locate available here: http://github.com/tomafro/bundler/commit/cc2ff2a76f141f6f57cb3a3806b045f821100dbb I'll create a fresh one for open some time tomorrow.

This is pulled, with both locate (via bundle show GEM) and bundle open, as 53e2de0.

Thanks.
