Move temperatureAdjustedFoo into the Temperature class. NFC.

And demagic all the callers of this function. Notice that with this
move, it becomes *harder* for these "getAdjustedFoo" functions to
access other contextual state, such as the state of the coderack
and the state of the workspace. This is a good thing for modularity
but possibly a misfeature in terms of flexibility-re-logic-changes.
