Usecase: Datatypes in hive are not highlighted without this fix

it seems `.cm-error` lost some specificity in [this commit](https://github.com/codemirror/CodeMirror/commit/a7d443ec82c1806d24e25ad8014a4d8651409320#diff-33646e9ee4d04eedb98a991a636c2302L35) that causes the error state to have same color as the tag.

Issue #3586

Including liquibyte theme with other themes causes other themes(when
in use) to not look right. For example there will be underline text
decorations when a text is selected in default theme.

...because the original blue on black background is difficult to read.

Also some general improvements to material.css and solarized.css

Was a little subdued

Spent quite a while perfecting this (IMO), but a lot of people seem to
really like it. Hope you do too.

So that selection inside widgets isn't affected

Issue #3342

So that they don't end up overriding more specific styles.

Issue #3325

Matches color for `cm-link` style

Margins for gutter markers aren't supported, and this was
pushing the numbers into the content.

Issue #3098

So that the contenteditable input style doesn't look silly
on desktop.

Issue #3053

This file was taken from
https://github.com/wisenomad/zenburn-lighttable-theme with a few
modifications to make it work in CodeMirror

The color white is not visible on the current backgroung

It doesn't belong in a theme.

Changed background selected color to #303030, previous #202020 value is too dark.
