cafe internal settings

[AlexMost]

Store local settings for separate project.

• app_root
• build_root
• path to recipe.json

This file can be placed in .cafe folder inside project root.

Having this in local settings we may omit those parameters in commands. This is not so necessary for existing functionality (build, watch), but it may be useful when we will want to do something like this :

cafe install js-lib jquery

cafe create spine-app omgapp

cafe js-libs :
/* here is list */

cafe spine-apps
/* here spine aps */

cafe aliases:
lib - alias
