Install script & new confs

The install script has changed a lot:

- It's checking if the files exists or not
- It installs pip if it's not there
- Some refactoring
- Showing warnings and ok
- It install fonts too

Vim is using jelleybeans colors for the console & it will never beep
again.

And I've changed terminator config to make it look like the normal
gnome-terminal.
