Improvements to help book

[Eitot]

Help books can now be localised with Crowdin. Crowdin supports localising HTML files:

For this to work, the source HTML files and localised HTML files should have the same structure. I went through the HTML files and:

1. removed all HTML files for locales that weren't localised at all,
2. updated the remaining HTML files to match the structure of the English HTML files and
3. updated the English HTML files to include some changes the French HTML files have (which seems to be the most maintained).

Some caveats:

• Crowdin uses XPath to find and match localised strings in the HTML files. This is not ideal, because making changes to the structure, such as adding a <p> somewhere, can cause Crowdin to remove and re-add all subsequent elements. I will be looking into this more, maybe we have to use <div> elements with id attributes to make the references clearer.
• Since the English HTML files are now the base for all other HTML files, individual tweaks can no longer be used. So far I only came across witdh attributes in table columns. However, these can be replaced with CSS.

The manual page warns that it "may be slow" to generate those. I will have to test. Maybe we need to provide the script's input files so that it runs only when changes are made to those files. That way it shouldn't interfere with incremental builds.

Speed is not an issue, but the result doesn't look promising:

I started by adding the German localization to the intro file :) Or is that an old one?

I did some digging and found that the "robots" tag affected the indexer. Those pages that have "keywords" or "anchors" as the value won't be indexed fully, i.e. none of the content, only metadata. This is why above the result was shown as (null). I fixed that by applying that tag to the title page only, which doesn't need to be indexed except for the anchors. I wasn't happy with the result of the --generate-summaries option, so I decided to add descriptions myself by borrowing the phrases on the title page (which some modifications).

I uploaded the updated HTML files to Crowdin.

Crowdin has the most recent version. It should be most up-to-date there. The German files miss entire sections and I find that there are many mistakes and weird phrases in the existing translations. :/
