Format and minify

[MaanooAk]

Improved format and added minify (in response to #24). Format is called when paste (the way it was) and also the are now two new options on the edit menu: Format and Minify.

• Format: I used js-beautify with custom options so the result is the same with the old ways but keeps comments. (There are some differences on the arrays of strings, but I think it's for the best.)

• Minify: In case the json is needed to be exported without all those spaces.

EDIT:

(There are some differences on the arrays of strings, but I think it's for the best.)

Realized just now that you were talking about this in #24 :)
