* colorpicker: fix opening error when color is undefined

* annotations: use tinycolor for working with region colors

Macaron's gzip middleware tries to automatically figure out the content
type for a file when gzipped and seems to mostly fail with plugin
readmes. This change sets the content type to plain text.

Fixes #9344. Ref #5952.

At least in my Postgresql 9.6.5, the old syntax of capitalized queries doesn't work (Linux).<br>
Running with UTF-8 as standard encoding and the ` notations didn't work either, so removed those.

This reverts commit 213ba037.

This modification aim to allow users to set value via textMapping and
these values to be used in background coloring as it text coloring.

This pull request closes #8404, but doesn't agree with #9012.
The issue #9012 consider that no coloring output should be put when
there is no data. I partially agree with this as I explicitely setted a
value in the textMapping I obviously want to treat `N/A` as a number.

`data.valueFormatted` contain the stringified version of `data.value`

If `Number()` cannot convert a string into a number a `NaN` value is
returned. So the code is still valid if the inputted value in
`data.valueFormatted` is not a number.

* updated the codeboxes in docs

* codebox change from json to http
