[nemo-preview] [feature request] Preview README with directory

[areynoua]

Hello,

It would be handy if nemo-preview on a directory also displayed (the beginning) of a potential README file in the directory in question.

I'm willing to help with the implementation, but due to lack of time, I would need someone to tell me where to start and where to look for documentation.

(It would also be nice to have a directory's README displayed somewhere when navigating in that directory, but that would require a UI redesign. Are there any plans to add a preview panel?)

Thanks!
