The previous API suffer different problems:
- It was difficult to handle articles redirecting to other article.
- It was not possible to get few information (title) without getting
the whole content.
The new API introduce the new class `Entry` that act as a proxy to an
article in the zim file.
Methods of `Reader` now return an `Entry` and the user has to call
`Entry`'s methods to get useful information.
No redirection is made explicitly.
If an entry is not found, an exception is raised instead of returning
an invalid `Entry`.
The common pattern to get the content of an entry become :
```
std::string content;
try {
auto entry = reader.getEntryFromPath(path);
entry = entry.getFinalEntry();
content = entry.getContent();
} catch (NoEntry& e) {
...
}
```
Older methods are keep (with the same behavior) but are marked as
deprecated.
