Installation instruction updates for Heroku

[cheeyeo]

Hi

I'm running Rails 3.0.8 and followed your instructions to try and get the engine into my refinery CMS.

Transpires that it should be cloned into vendor/engines/memberships else bundler will not be able to find it during deploy especially onto heroku.

Also the git submodules within the memberships engine directory needs to be removed before deploy to heroku.

Hope it helps

I am having trouble deploying to heroku, it says "Could not find refinerycms-memberships-1.0 in any of the sources"

I have already cloned it into /engines/refinerycms_membership

Any ideas?
