.bashrc and PS1 Environment

The combination of this .bashrc file and the PS1 variable makes my very useful PS1 prompt.

This config below will:

• Make a very useful looking PS1 showing all adaptor IP addresses

• PS1 will show date and time of command

• Every command executed in bash will be logged to ~/.logs/.terminal_log/
