Revert "Ensure log dir exists. Fix whitespace."

This reverts commit 025c15025eac27fc183f860dae9600ccd4fa3032.
Model compiler abstraction layer (model_manager)

Abstraction for boss_record_compiler and boss_record_lib.
It allows people to implement custom model compilers
alternative to a stuff packaged with boss_db.
Everything is controlled by {model_manager, _} option
in boss.config.
Boss_db dependency remains.

Merge pull request #112 from bipthelin/vsn-gitfix

No need for special case when in rel dir.
Added set_cookie to start_dev command.

First step, I'm working on a rake task like rebar system that
should work on prod and dev environments.
Support for session cookie domain.

If session_domain boss.config option is set, the session cookie inserts
the Domain=x option.

This enables subdomain apps (*.domain.com), ex:
{session_domain, ".domain.com"}

simple_bridge does not support this option in the :cookie method, used
mochiweb util (currently is allready a non-webserver-dependency).
