Squashed commit of breakfast/brunch commands
Add a CM-specific breakfast menu

We usually don't wan't all the devices in the lunch menu, so
we can now choose to pick up breakfast or brunch and get a
smaller selection of devices (i.e., those we support)

Make brunch more nutritious

* "breakfast device-name" will set up the environment, just like lunch.
* "brunch device-name" will actually do the whole setup and build :)

brunch: add a lazier mode

Since all of CM's targets have a predictable PRODUCT_NAME and BUILD_VARIANT
(i.e., "cyanogen_$(PRODUCT_DEVICE)-eng"), brunch can now be invoked passing
just the PRODUCT_DEVICE ("brunch passion" for the N1 setup+build, for
example).
The "classic" long form of $(PRODUCT_NAME)-$(BUILD_VARIANT) can still be used
if desired ("brunch cyanogen_passion-eng" still works).

breakfast in bed

breakfast in bed (aliased to "bib") is the baconless friend of lazy
brunch.
You can now use "breakfast passion", or "bib passion", to setup the
corresponding CM build without actually building it

Fix breakfast for the undecided

The menu presentation (i.e., giving no arguments to breakfast
or brunch) was broken, so if you didn't know the name of your
target you weren't given a list to choose from, just an error.
