Update the manual's wording for preset inheritance

Add links between two nodes in the manual

Pass correct height when setting the 'bold' face

This fixes a regression introduced by commit fa00972.  We would get an
error when invoking 'fontaine-set-preset' with a prefix argument.

Tweak markup of proper code symbol

Update backronym

I have had this version on my website for a long time.  I like it
better.

All my packages (and their backronyms): <https://protesilaos.com/emacs>.

Add informative :tag to weight selection widget

Make it possible to inherit a preset in another preset

Update copyright years

Bump version to trigger package rebuild

This is to offer commit fa00972 to users.

Remove faulty height from bold face

I discovered this by troubleshooting the problem reported by Joe
Higton on the ef-themes mailing list:
<https://lists.sr.ht/~protesilaos/ef-themes/%3C87mta80vtk.fsf%40heartofgold.mail-host-address-is-not-set%3E>.

It is a mistake to set a :height attribute for bold, as it should not
anyhow affect the underlying text beside the :weight and :family.

Update to version 0.4.0

Remove old obsoletion form

Reword manual on persisting font configurations

Remove FIXME about x-family-fonts

It works on my --with-pgtk and I will assume it works elsewhere as well.

Add :package-version to all defcustom forms

With this we can inform the user when a variable was introduced or last
changed.  The information appears in the Help buffers.

Add FIXME for error cond in fontaine--apply-preset

Declare and document fontaine-apply-current-preset

Re-indent code in fontaine.el
