add kanji-dictionary lookup

Hi!
I wonder if it would be possible to add a menu option: search in dictionary
It would link to external websites or to existing apps on the android device

For example, "Japanese Kanji Study" is a very detailed app. And it would really be great if it can be opened at the right page for the kanji we are studying with ringotan.

When we are learning a kanji, we could click on "additional lookup" and click on one option:
- jisho.org
- kanji koohii
- weblio.jp
- kanji study app (if installed)
- ...
