(cherry picked from commit 29f1e334ab140f84ac1057c2cc6623cb291b2827)

Sphinx does not appear to automatically find the favicon anymore.

build sections

- Update screenshots in Introduction for users coming from photoshop.
- Update screenshot for fill layer dialog

- Remove Quattrocento Sans font and use Lato for everything, this makes
it consistent and the header font is now distinguishable for header
below h3

- Remove 0 margin from header to differentiate better

- Increase font size to 18 to make it easy to read.

- Restrict maximum width to 1100px so that on screen with larger
resolution don;t have one long line across the screen

One of the urls in the krita_manual_readme.rst had an extra .git
The urls in intro_hacking_krita.rts pointed to the documention
repository instead of the code repository.

- Added images of icons to corresponding layer properties of the
colorize mask

- Remove all unused images
- Remove a dead link to hushcoil brushes in resource page
- Fix image directive in gitlab documentation for manual
- Remove a duplicate page for shape selection tool
- Remove the playstore and apple store url warning in FAQs page
- Remove a warning because of typo from edit menu page

Mainly around:
- outdated links;
- wrong word quoting;
- typos, misspelling, missing words, etc.

It also explands and fixes a bit the description of a configuration file.

Update reference_manual/tools/fill.rst, reference_manual/tools/rectangle.rst, reference_manual/layers_and_masks/fill_layers.rst files

All it took was

pandoc README.rst -o ../docs-krita-org/untranslatable_pages/build/building_krita_with_docker.rst

They are not needed.

And move the specialized build guides into a subfolder
