Modernization

[glaszig]

i realize this is quite a bucket of stuff but i couldn't help myself.

• elevates supported ruby and rails versions to 3.0 and 7.1, respectively, as ruby 2 and rails < 6.1 are EOL
• eliminate database requirement as nothing in this gem is actually needing one
• convert coffeescript to vannilla js
• get rid of jquery; no need to bother users with an additional 20k of js
• position dialog with pure css
• bumped version number to 4.0.0
• move off of travis

resolves #121, #132.

This is awesome; I just want to do a check myself that the CS to JS matches my own output (if you can let me know if there were any additional changes you made that would be helpful) and I'll get this merged ASAP.

[glaszig]

quite a bunch has changed when ripping out jquery: ab263ea...364f156

[glaszig]

don't hurry. please have proper look. i tried to do my best but i'm sure i missed things.

@gregschmit any update ?

[glaszig]

i adjusted for rails 7.1. should be ready to be merged.

[gregschmit]

Sorry everybody; a lot of crap in my life has conspired to keep me away from this. I am just going to do some basic testing on a demo app (and I'll likely also test this in active scaffold and active admin) to ensure nothing breaks and then I'll merge this. I'm hoping to get to it within the next day or so.

[glaszig]

fwiw, there’s the dummy app that gives you a bunch of selects fo play with.

[gregschmit]

Yeah I remembered that as soon as I hit enter -- I was thinking of another project I'm working on where one of my tasks is to build a demo app for it.

[gregschmit]

Ok, gonna merge this now as it looks good to me.

[gregschmit]

Thanks @glaszig!

[gregschmit]

Also thank you @fwininger -- everyone please feel free to @ me on PRs and issues that you believe are important for this project. There are a lot of old PRs so it's hard to separate signal from noise so if you @ me then there's a good chance I'll merge it.
