MAJOR CHANGE: Rename "konsole" to something else

[bitspittle]

The name Konsole sits too closely to KDE Konsole, which is confusing.

So, this bug is a few parts...

1. Remove all references of the name "konsole" from class, method, and variable names, e.g. konsoleApp -> session and konsoleVarOf to liveVarOf
   • Once this is done, the code itself will no longer care about large refactorings of name changes in the future.
2. Come up with a new name for the library. I'm leaning on "Kotter" for "KOTlin TERminal" but I'm open to other ideas
3. Update the package / artifacts / README / screencasts / this repo name / our Discord channel etc. to match

This is a pretty big change for this library. This may inconvenience users who are using it, so I'll give this bug a day or two just in case anyone wants to respond. But so far, I haven't seen much of an indication that people are actually using it yet, so it seems like a good time to make such a drastic change.

Actually, I'm going to commit to this soon, so I can clear my plate for other work tomorrow.

If this caused anyone confusion or trouble, please let me know in this bug report so I'll know I should have been more careful next time.
