Improvements done to IRC channel #crux-arm bots at freenode

After some time without touching these services, we finally have activated in IRC #crux-arm channel those services.

First, we have changed git hook script used to notice users about git commits about newer ports updates.

ON another hand, we have updated our log bot version, after some changes made by Jose (sepen). After some days testing them on an isolated enviroment, we have verified a big stability bump.

We hope in this way that users connected to IRC get more information.
