Allow configuration of testFuncNames

In test-mode, an attempt is made to give function names deterministic IDs. With the ID calculation being based on the stacktrace, there are scenarios where the same ID is providing for differing functions, the practical impact of which, can be "User clicks button B, Lift reacts as if user clicked button A".

Currently the only way to disable this test feature is to wrap code in S.disableTestFunc which can be impractical if required more than a few times. More configuration of this behaviour is desired. (Example, disable completely, disable for particular snippet/request.)

So, @japgolly is this satisfied by the existence of funcNameGenerator? I noticed this thread predates that implementation...

Oh hi @farmdawgnation. Yes, I am. I submitted the patch that provides LiftRules.funcNameGenerator. I think this issue here being open is an oversight. I must've forgotten to close it after the others patches got accepted. Sorry about that! Closing...
