Conda virtualenv prompt support

Nobody has claimed this yet.

I'm trying to include highlighting of the conda virtualenv in the `.bash_prompt` file, but I'm not very familiar with bash and haven't had much success in targeting it. Say this is the desired result for some virtualenv named `temp`;

``` shell
username at host in ~/dotfiles on master [+] < temp >
````

Currently, the conda virtualenv name is prepended to the command prompt. I believe that is the default behavior;

``` shell
(temp)
username at host in ~/dotfiles on master [+]
````

I can't get it to work and this is as far as I got by looking at bash-it's [powerline theme](https://github.com/Bash-it/bash-it/blob/76e4659126014b695ec2f01a14491bce7aa7e2a1/themes/powerline/powerline.base.bash#L55) and [here](https://github.com/jchaps/dotfiles/blob/dac2598dff6919bfed53d8ac0788dd6f10ca365d/system/prompt#L93);

``` shell
# Highlight the Conda environment.
if [[ "$CONDA_DEFAULT_ENV" != "" ]]; then
condaStyle="${white}:$CONDA_DEFAULT_ENV";
else
condaStyle="";
fi;
```

and included in the existing prompt with;
``` shell
PS1+="\[${condaStyle}\]\n"; # conda
```

Start in the `.bash_prompt` file and trace how `PS1` is assembled. Check how `CONDA_DEFAULT_ENV` identifies the active Conda environment, then place that value in the prompt format shown in the issue. Done means an active environment such as `temp` appears in angle brackets without the default `(temp)` prefix, while prompts without Conda remain unchanged.
