Created a shell cli for the Obsidian URI

It’s over here: obsidian/obsidian_cli at main · bithead2k/obsidian · GitHub

Hoping to find people that want to fix it up for Windows and Mac.

Also, I’m having a hard time with the mime integration on Linux. Can’t seem to get the .desktop file right, so I just stuck in a hard-coded invocation. Somebody please correct me.
