Since the available lexers might change with a different version of pygments, it would be handy to have an option that just outputs the list of lexers supported by the selected pb instance.
Technically, this has no prerequisites, but it would be odd to support it before lexers themselves are supported. So, consider #15 a soft pre-req.
In addition to the /l route that pb offers, there is also a /ls route to list supported styles (pygments themes). Adding --list-lexers and --list-themes should be pretty easy.
