Added project name display using projectile

[berylllium]

I've added a completely optional feature allowing users to display the name of the project the current buffer is in by using projectile. Projectile is a completely optional dependency here.

I've also changed the elcord--details-and-state function so that future additions would be easier.

At a glance this seems cool! I'll review later when I get a chance to properly look at the code and try it out. Thanks for contributing!

Ditto, I like the idea of project integration. Looks good but I'll review more in the morning. Thanks!

LGTM, but I'll let @Zulu-Inuoe review as well 😄

Yep sorry about the delay. Had a busier Friday than expected. I did take another look and I'm good with it

Great news! I was away for a few days so I couldn't reply. I thought a bit about the limitation of only being able to display either line numbers or the project name; maybe display the line numbers in short form after the buffer details line like so: Editing elcord.el [91 of 1002]. And also add an option to do so even without the project name setting turned on.

Maybe an interesting idea ¯\_(ツ)_/¯.

P.S.: I have very little knowledge about contributing to open source projects, so lets say I'm interested in trying to add said feature, would I just add commits to this request, or create a new one? Any help would be appreciated!

Sorry! I thought I already replied to this! I think maybe the best answer is to provide some sort of hook for a user to be able to override the details in their own configuration. The default value for this function would produce the line number text, but adding projectile for example would be as simple as overriding this function with something else that returns the project name.

Feel free to add to the current PR if you think that's something you'd like to work on. If not, I feel comfortable merging it.
