Title: API Deprecated Profiler class, removed related debug GET params

Use third party tools like XHProf instead.
Removed defunct or unnecessary debug GET parameters:
debug_profile, debug_memory, profile_trace, debug_javascript, debug_behaviour

Rationale: Its been created in a time where third party profilers
weren't as useful as they are today. It clutters the core code,
adds unnecessary global dependencies. And its very selective
in what it profiles (just happens to be the stuff we thought would
have the biggest performance impact).

Sending pull request against master, as it shouldn't go into the 3.0 branch (and the 3.0.1 release)
