Replace separators by spaces in title before searching

[tetraf]

Regular words separators (I've tried with dots, dash and underscores) aren't replaced before searching in database. Example:

$ kolekto import big.buck.bunny.ogg 
Title to search [big.buck.bunny]? 
No results to display for the file: big.buck.bunny.ogg
$ kolekto import big.buck.bunny.ogg 
Title to search [big.buck.bunny]? big buck bunny
Please choose the relevant movie for the file: big.buck.bunny.ogg

[1] Big Buck Bunny (2008) by Sacha Goedegebure [tmdb_proxy]
[2] Enter manually informations
[3] None of these

Choice [1-3]?
