Refined both ethernet implementation and GSM. Now the system calls and texts a pool of predefined phone number when the system is alarmed; it also answer with a confirmation SMS when the system is enabled/disabled through GSM.

I want to replace ENC28J60 with W5100 for many reason: simpler and more powerful library, no need for external script for sending mail, better reliability.
