Replace Foundations w/ Why automate? and File naming

[libcce]

As discussed @ccronje @sharilaster @ppival, Foundations is now two episodes:

• https://github.com/LibraryCarpentry/lc-data-intro/blob/gh-pages/_episodes/09-why-automate.md
• Create new file naming and formatting episode #136

The File naming episode is a PR that needs to be approved/merged by one/all of you. If we are fine with this, I can update the episodes to reflect these changes. @sharilaster I included a very basic challenge of working with Markdown in File naming. What do you think? @ccronje I added a link to the UNIX Shell lesson at the end of File naming. Is this what you were thinking?

I merged the PR above so the two episodes to consider are:

• Why automate? https://github.com/LibraryCarpentry/lc-data-intro/blob/gh-pages/_episodes/09-why-automate.md
• File naming https://github.com/LibraryCarpentry/lc-data-intro/blob/gh-pages/_episodes/10-file-naming.md

to replace Foundations https://github.com/LibraryCarpentry/lc-data-intro/blob/gh-pages/_episodes/03-foundations.md

As we discussed via our teams site, @sharilaster @ppival @ccronje what do you think? Ready to make this change?

[sharilaster]

They look good. I think a different name might be helpful for "File naming" since it also covers plain text -- what about "Machine-friendly practices" or something like that?

[sharilaster]

Or "Machine-friendly foundations"?

This all looks good - thanks @libcce @sharilaster! @sharilaster is the title "File naming & formatting" ok?

Would you like me to delete Foundations? Was there any discussion at the sprint on the order of episodes? Would you like the new ones to sit in their current spots?

Hi @ccronje @sharilaster discussion here #142 on what happened in the 2nd lesson sprint at CDL.

Now that we have an overview lesson https://librarycarpentry.org/lc-overview/ I'm going to close this issue, remove the two new episodes:

Why automate? https://github.com/LibraryCarpentry/lc-data-intro/blob/gh-pages/_episodes/09-why-automate.md
File naming https://github.com/LibraryCarpentry/lc-data-intro/blob/gh-pages/_episodes/10-file-naming.md

I'm leaving Foundations for the moment and opening up another issue for us to review the overview.
