4942767c4d More default "weird" tuning for the "SYN_with_data" notice.
- I think the default tuning should be that anything not requiring
  a session to be established should use ACTION_LOG_PER_ORIG.

- We need to get some tie-in with the metrics framework in place
  so that we can find when lots of these values are being suppressed.

f0b32b21ee weird.bro rewrite.
- I want to test it for a short while before committing it to
  master just to make sure it is a sane modification.

5a04190ffe More adjustment to reduce Weird volumes.
- New script extracted from weird.bro to implement the
  connection related "weird" data into an optionally
  loaded script.

- Adjusted the default notice tuning to stop ignoring
  the connection related weirds since they aren't loaded
  by default anymore.

11c437faa3 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.

47500ceef4 Add a test that checks each individual script can be loaded in bare-mode.
Fixed most @load dependency issues in the process.  The test is still
failing in a "known" way due to hot.conn.bro and scan.bro.

597a4d6704 Hopefully the last major script reorganization.
- policy/ renamed to scripts/

- By default BROPATH now contains:
	- scripts/
	- scripts/policy
	- scripts/site

- *Nearly* all tests pass.

- All of scripts/base/ is loaded by main.cc
	- Can be disabled by setting $BRO_NO_BASE_SCRIPTS
	- Scripts in scripts/base/ don't use relative path loading to ease use of BRO_NO_BASE_SCRIPTS (to copy and paste that script).

- The scripts in scripts/base/protocols/ only (or soon will only) do logging and state building.

- The scripts in scripts/base/frameworks/ add functionality without causing any additional overhead.

- All "detection" activity happens through scripts in scripts/policy/.

- Communications framework modified temporarily to need an environment variable to actually enable (ENABLE_COMMUNICATION=1)
	- This is so the communications framework can be loaded as part
	  of the base without causing trouble when it's not needed.
	- This will be removed once a resolution to ticket #540 is reached.
