Update EDICT

[ashchan]

Fetch newest EDICT from edrdg.org and write a script to convert to JSON, or just read directly to Swift.

Note: prefer the JMdict or EDICT2 format. As:

There are now two EDICT versions:

A. the plain EDICT file. This is the original format, where there is only one kanji form and one reading per entry. I regard this as a legacy format, and only provide it for older applications. PLEASE do not use this format for new applications, as I would like to withdraw it one day.
B. the enhanced "EDICT2" format. This can have multiple kanji forms and readings in an entry, and also has other information such as cross-references, restrictions, etc. and also uses kanji from the extensions in the JIS X 0212 standard. It has almost all the information in the full JMdict format. This form should be used for all new applications.

edict2u should be used since it's UTF8 encoded, while edict2 is EUC-JP.
