Mustache 4 was release in late october 2019 and is not compatible with kiwix-lib as is.
Replacement in taskbar is messed-up and breaks suggestions.
Until this is fixed/adapted, inform users to use version 3.
if a link contains nested elements like `<a href="http://somewhere"><strong>goto</strong></a>`
then the link is trigger by the `<strong />` element which has no `href` attribute.
We were thus releasing the event in this case, resulting in legitimate external links
not blocked.
We are now looking for the closest `<a />` parent (might be self) to retrieve the `href`
attribute and capture if necessary.
- `setBlockExternalLinks()` on server
- zero-dependency JS code
- JS script added in `inject_externallinks_blocker()`
- changed URL to `/catch/external?source=<source>`
In many use cases, it is not wanted to have user accidentaly click on external links
and leave the served ZIM content.
This could be because the result is unpredictible (reader not implementing this properly)
or because the serve user knows there's no backup internet connexion or because there is
an induced cost behind external links that doesn't affect served content.
using a new flag (`blockExternalLinks`) on `Response`/`setTaskBar`, a piece of JS code
is injected into the taskbar code.
This code adds a JS handler on all link click events and verifies the destination.
If the destination appears to be an external link (1), the link target is changed to
a specific URL:
```
/external?source=<original_uri>
```
(1) external is a link that's not on the same origin and starts with either `http:` `https:` or `//`.
Server implements a new handler on `/external` that displays a new page (`captured_external.html`)
which returns a generic message explaining the situation and offering to click on the link
again should the user really want to.
This is done by specifically asking `set_taskbar` to not block external requests on that page.
This approach allows integrators using a reverse proxy to handle that endpoint differently (rebrand it)
1. `Server` now has an `m_blockExternalLinks` defaulting to `false`
1. `Server.setTaskbar` is extended to support an additional bool to set the variable.
1. `Response` now has an `m_blockExternalLinks`
1. `Response` constr expects an additional bool for `blockExternalLinks`.
1. `Response.set_taskbar` is extended to support an additional bool to set the variable.
1. JNI/Java Wrapper reflects the extensions.
1. New resource file `templates/block_external.js` (included in head_part). Should it be in skin?
1. New resource file `templates/captured_external.html` for `handle_captured_external()`
1. Added a comment on `head_part.html` to help with JS insertion at the right place
1. `introduce_taskbar()` conditionnaly inserts the JS inside the taskbar
We must correctly quote path with space on windows.
This is needed as we can't launch command using a array of string on
windows but by giving only one string using space as separator.

No real change. Reordering setting and dumping of attribute in the same
order (mostly) they are declared in book.h make it easier to detect missing
attribute.
Downloader::startDownload has a new parameter option which is a vector of
pair that represents the options that can be set for adding a uri with aria2
with the function Aria2::addUri.
Aria2::addUri uses this parameter to set the struct of parameters for the
aria2 command
