Proposal of features such as Net classes, Date and a new theme.

[Rollbacke]

Add RAM free, Disk used percent, Class Net, Class Date and bash-dark-green theme.

[Rollbacke]

All themes are filled. Normally, I tested everything.

Hello @Rollbacke
Thanks for this PR!
I see that you and @RussNelson opened almost the same PR, so i will not be able to merge both.

@RussNelson can you confirm the PR #65 and #67 are from @Rollbacke's code?
If so, would it be OK to close them and merge only this PR which has both?

[mathoudebine]

Is it possible to avoid using an external file?

[Rollbacke]

Sorry, I haven't found how to do it yet.

[Rollbacke]

Found how to do without temporary file.
I pushed the commit (below).

Hi @mathoudebine,
These are indeed my proposals that I had put in the Issues.
I cleaned up and improved the code.
From what I suggested:

• for the Net class, contained unnecessary lines and lacked checks that can crash the script (if the interface doesn't exist, it doesn't work).
• for the Date class, since I wasn't using the strftime function, the date displayed "3-11-2022", which doesn't look pretty. With strftime, this is "03-11-2022".

In addition, I modified all of the themes (theme.yaml) to make it work.
I added the theme bash-dark-green I made myself.
I also added two metrics: RAM free, Disk used percent.

[Rollbacke]

Oh. Sorry about that. I will fix that.

[Rollbacke]

It's OK ;)
