Title: Coloured virtualenv name in prompt ($PS1)

- A more visual way to know if the virtual environment is currently activated.
- The virtual environment name at the beginning of the prompt ($PS1) will appear in color.
- By default the color green is used. This can be changed using
'export VIRTUAL_ENV_PS1_COLOR=$COLOR_CODE' before sourcing activate script.
- For bash only.
