Seth Hall 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.
