Vim-like Error Handling

[orbisvicis]

The command: AddTabularPipeline<CR>

SkyBison's errors:

Error detected while processing function SkyBison..<SNR>74_RunCommandAndQuit:                                                                                                
line   12:
E471: Argument required: AddTabularPipeline
Press ENTER or type command to continue

Vim's errors:

E471: Argument required

Suggestion:

Wrap RunCommandAndQuit in a try/catch, and echoerr v:exception, then exit normally.

Not sure what order you'll view these in, so I'm going to prefix all of the recent issues you've made with:

I've got a skybison 2.0 ~90% done with many improvements. There's some (external) blockers keeping me from finishing and publishing it (and a bunch of other vim projects of mine...) immediately, but I fully plan to do so as soon as is reasonably possible.

Sounds good to me. I'll do so for 2.0.
