Simplifies the build tooling a teeny bit.
This data file shouldn't need to be updated for v3 ever again.
This task will also be unnecessary in v4.

Now we are on par with what we have on the gh-pages dist/ folder.

This reverts commit e31c2edf.

This reverts commit 25ca5131.

Big thanks to @gvas for https://github.com/axemclion/grunt-saucelabs/pull/136 ! <3

Works around #13914.

We might give it another go in the future but the stuff this breaks over the time does not justify having it enabled. The gain in size is negligible:

dist/css/bootstrap.min.css: 108.65 kB → 109.5 kB
dist/css/bootstrap-theme.min.css: 18.84 kB → 18.86 kB
docs/assets/css/docs.min.css: 20.44 kB → 20.61 kB

Will hopefully revert this reversion and land a fully-working version of UMD in v3.3.0.

Instead of our homegrown grunt/shrinkwrap.js
Fixes #13483.
New npm-shrinkwrap.json is human-readable but still in a consistent/stable format.
Should aid debugging, produce better diffs, and be less prone to merge conflicts

Refs #13842

Closes #13795 by merging it.

Also use the official filenames.

Be more consistent across the whole codebase.

Also, make use of JSHint's 2.5.1 `extends` and `qunit` options. This way we set our basis options in js/.jshintrc and override the rest.

Reassigned minification of CSS files from the less task to the cssmin
task

Most folks shouldn't care about the shrinkwrap.
It should only be run on-demand, not as a routine/periodic thing.

Fixes #9951
Fixes #12865

Closes #12987
