Add light theme

[vladshcherbin]

It would be cool to have a light theme out of the box, there are a lot of white terminals. Currently it looks like this:

It would be nice to have a couple of pre-built themes.
I'm thinking something like igniculus('light'),
'light' being the name of one of the available themes ofc...

I'll add it as a planned feature for next release. Default theme would remain the same so its non-breaking.

@Undre4m maybe it's better to make it as an option, to be like the other options. Style related options to define in a nested group, smth like:

igniculus({
  theme: 'light',
  styles: {
    comments: { mode: 'dim', fg: 'white' },
    constants: { mode: 'dim', fg: 'red' },
    ...
  },
  prefix: ...,
  postfix: ...,
  output: ...
})

Yes, it's a breaking one, but a good one for a future run since more options may be needed later and now options are already in mess (styles, prefix, postfix, output together).

What do you think?

@vladshcherbin yes, separation of style-related and option-specific configurations is something i've been wanting to do but haven't had the time. It's an issue for version 2.0, among others. Probably something like:

igniculus({
  prefix: {
    style: { fg: ... },
    options: {  text: ... }
  }
})

I do like the idea of a theme option, i think is the way to go; defining an optional pre-built theme to use, and being able to add/override specific options by the usual manner.
