Added a levenshtein 'check' to the /data command.
If you make a typo, it will try to correct it automatically by comparing the levenshtein distance.
Fixed style issues; removed whitespace on empty lines and moved levenshtein function to tools.js
Moved the levenshtein search to tools.js
Added an optional searchIn parameter to Tools.searchByLevenshtein
If you want to search through 'everything', omit it.
If you want to search through moves alone for example, provide ['Movedex'] as second parameter.
