[Toaster] [PATCH 01/20] toaster: don't allow to run toaster as a script

[Ed Bartosh]

Removed support of starting toaster as a script.

Sourcing a toaster script becomes the only way to start it.
It's consistent with the way oe build system is started by sourcing
oe-init-build-env. It also returns user back to shell, so user can
continue running builds without having to open new terminal window.
