Clojurians Log v2

Hello alda users! I updated [language-alda](https://github.com/MadcapJake/language-alda/releases/tag/v0.4.0) to support the latest changes to alda syntax. Hope you like it. Don't forget to submit issues if you find something that needs fixing!

looks awesome, thanks @madcapjake!

one thing to consider about automatically adding : after instrument names is that sometimes you may want to specify multiple instruments, e.g. trumpet/trombone/tuba:

oops! you're right!

btw, if anyone has thoughts on Alda having a long-comment syntax again, please let me know your thoughts! https://github.com/alda-lang/alda/issues/142

i have a feeling alda 1.0.0 is on the horizon, and it would be good for us to nail down the "official syntax" before then

i could also use more input on this: https://github.com/alda-lang/alda/issues/103

Fixed instrument snippet: first instrument places the colon (and allows you to <tab> from before to after if you have no extra instruments or a nickname) and subsequent instruments provide non-coloned completions. Nicely, atom lets you <tab> through to after the first instrument's colon for free!

nice!
