[RFC] [WIP] [Draft] J.A.R.V.I.S.

Just Another Runner and I'll come up w/ sth. for the rest… later.

Ever unhappy w/ most available runners, the idea is to have a convenient cross over between genericrunner™ and a (quake like) terminal window which always seems in the way.
So the idea i hacked up last night is single line shell in an (ideally override-redirect) window that allows me to run stuff but also dynamically expand for a growing set of functions (shadowing popular binaries because I'm not re-learning this…) so that I can use it to inspect file, check top, control mpd etcetc. in space and then auto-hides when losing focus.

This way I get a runner w/ the autocompletion comfort of zsh/bash/thereareactuallysomefishusersinthisforum and transient access to a terminal that will be neither to large nor no small nor on a different workspace nor stashed below a bunch of other windows nor obstructing them.

The code below is "runnable" but full of hardcoded local stuff (urxvt, fonts, background images, another script that allows me to align to daylight etc.)

=> What I want to know at this point is whether this is self-masturbative nonsense or there's enough interest in the principal idea to generalize it into a distributable program (modular function extension, configurable VTE, less hardcoded binaries, stuff).
