Logging framework update and mass Log::ID renaming.

- Log path's are generated in the scripting land
  now.  The default Log stream ID to path string
  mapping works like this:
    - Notice::LOG -> "notice"
    - Notice::POLICY_LOG -> "notice_policy"
    - TestModule::LOG -> "test_module"

- Logging streams updated across all of the shipped
  scripts to be more user friendly.  Instead of
  the logging stream ID HTTP::HTTP, we now have
  HTTP::LOG, etc.

- The priorities on some bro_init handlers have
  been adjusted to make the process of applying
  filters or disabling streams easier for users.
