NFC Dicts Manager

[grugnoymeme]

Application Submission

Backup system and user dict. Easly manage more than one dictionary to avoid long dictionaries attack, setting the one you need ad system or user dict temporally. Merge 2 dictionaries to make one stronger. Optimize merged or not merged dict to delete duplicates keys, keys out of range of lenght, keys with characters out of the HEX value (0-9, A-F), uppercase all keys...

I probably will add some features like edit one dict, searching keys in one dict and maybe something else...
