Levenshtein-based search

========================

The levenshtein attribute maintains an index of keywords across other attributes which can be searched using the 

levenshtein algorithm.

There is a filter rule that enables a similarity search via the created index. Optionally, an auto-completion

("Vanilla Script") can be activated (please note the template selection).

Adjustment of the index table

-----------------------------

The fields for storing the index can be enlarged as required e.g. from a length of `64` to `256`.

To do this, create a corresponding DCA file and adjust the values. (Note: the keys and the file name still

have the old, wrong notation with "sth").

```php

// contao/dca/tl_metamodel_levensthein_index.php

$GLOBALS['TL_DCA']['tl_metamodel_levensthein_index']['fields']['transliterated']['sql'] =

    'varbinary(256) NOT NULL default \'\'';

$GLOBALS['TL_DCA']['tl_metamodel_levensthein_index']['fields']['word']['sql']           =

    'varchar(256) BINARY NOT NULL default \'\'';

```
