bin/robot script is created from the robotframework entrypoint and not from plone.app.robotframework

[wesleybl]

As a result, the plone.app.robotframework egg is not inserted into the path and its keywords are not recognized.

This happens because the robotframework is installed directly in Python. When this occurs, buildout gives preference to packages that are in Python when it finds the package corresponding to the script.

This was done by @datakurre in #872. @datakurre, why do we need to have a robotframework directly in Python? This seems to be something to get the editor to work. Couldn't this be done locally, only for those who need it?
