Translations through line 1373

I ignored most of those English things needing translation from English
to Japanese. I am not really qualified to do that properly yet. :(
Translations for lines 1373 - 2097

Japanese insufficient or missing at the following lines:

1430 日本語がない
1467 タイプが指定されたら、そのタイプのリスナーだけを消す。指定されていないなら、全部を消す。
1695 ロードされた画像だけを指しているが、画像も音もロードできるから

I don't know Japanese programming terminology well enough to fix these
myself. The notes are in Japanese because they are likely to be fixed by
a native speaker... and if not, I presume notes in Japanese will pose no
problem for whoever does fix them.

Japanese translations also needed for most of enchant.Event.
enchant.Event is before line 1373, but I forgot to make this note in my
previous commit.
Translations through 2386

Translation notes:

2359: Redundant, I know, but that's what the Japanese says.
2360: Is the delay parameter in miliseconds?
2384: Also redundant per Japanese.

Code notes:

2386: Added label for time parameter to documentation, but with no
explanation. Is it in miliseconds?
