Add syntax highlighting using pygments.

[bellecp]

It looks nicer with some color highlighting, which comes for free using pygments and its guess_lexer smart function.

The few lines of code come from http://pygments.org/docs/quickstart/

(nice idea btw!)

Nice. I like.

I like the idea of colorization but I think it may need to be more specific than the default guess_lexer. I tried the following commands:

$ howdoi format string bash
$ howdoi print stack trace python
$ howdoi convert mp4 to animated gif
$ howdoi create tar archive

Of all the commands only two were colored, and of those the only symbols that were selected for color were "for", "${", and "$}"

You might want to take a look at this comment and try to implement some of the suggestions.

It now finds a lexer based on the first argument/tag matching a pygments lexer.

Duplicate: #24

Thanks for this request. I'm evaluating it and #24 and will provide feedback once I have tested both.

After playing with this commit and #24 I prefer this version. The highlighting is nice but I find that it can sometimes be too intrusive. What do you think about colorization being optional through a flag (-c / --color)? If you want to permanently enable color you would include the following alias:

alias howdoi='howdoi -c'

[bellecp]

I merged your master branch and updated the code with a -c, --colorflag. It seems to work smoothly.

My favorite setting is with --alland --color--:

howdoi -c -a C++ for loop

I feel it's often preferable to have the full (colorized) answer, where so much can be learned... But I let you choose what the default behavior should be.

Thanks @pierroweb! I'll take a final look this week.
