We always need a humanReadableName associated with a content to search in.
Do not separate the two values (human readable name and zim) in two
different functions.
This way, we avoid miss-use of the Searcher who could lead to segfault.
Add a `title` write argument to `getContent*` methods.
This argument is filled with the title of the content get.
Also update the JNI accordingly.
Related to kiwix/kiwix-android#214
This was not necessary when searching in only one zim file as `url` was
enough to get the article (and so the content).
If we want to search in several zim in the same time, we need a way to get
the content directly.
If a embedded fulltext database is present, suggestion will search in it :
- insensitive case search.
- search for terms in the middle of the title.
- xapian will try to complete the last word of the query (as if a '*'
were added at the end)
Compilation fails on clang 3.4.1 (and presumably later, tho I haven't tested) with
```

because we are not using the right type for the map iterator. As we are using
C++11, let's use `auto` and make compiler set the right type for us.
Android will look in specific repository to find native libs.
We need to use the `android_abi` name defined in the cross_compilation
file instead of `cpu_family`.
libzim only know how to read embedded full text index in a zim file.
This is nice as we want to embedded the full text index in zim file and
not have separated full text index.
However, we still have some zim+separated index we have to read.
So we have to support the search in separated index for a while.
`kiwix-android` is using `kiwix-lib` as an external java application now.
So we need `kiwix-lib` build system to also install application files
(manifest, resources, ..).
In C++11 `linux` is not a reserved word, so compilators do not define it.
A correct way to check if we are compiling for linux is to check for
`__linux__`.
