core: logging refactoring, first step:
- added a core.log module
- 3 backends can be used: basic, standard (python's logging module) or twisted
- colors can be used
- the module has been made to be used by frontends, it should work in exotic environments like pyjamas
- logging basic configuration is now made in sat.tac
- core.log configuration is inspired from python standard logging, and use it when possible
- getLogger should be used the same way as for standard logging
