🐛 [fix] Fix a bug of not-localized About view

[juggernautjp]

I fixed a bug for the issue #301.

Not fixed bugs

I can not the following two bugs. Need help.

1. After click the "Check now" button

1. Select [File] -> [Settings]
2. Click [Packages] in the "Settings" view
3. Click "Setting"in the "atom-i18n" package
4. Select "日本語 (ja)" as "Language" item
5. Click "Atom について" (en: "About Atom") tab
6. Click "更新を今すぐ確認" (en: "Check now") button, which is the right side of "Atom は最新の状態です！" (en: "Atom is up to date!")
7. The, localized "Atom は最新の状態です！" is replaced with "Atom is up to date!"
8. Also, "Checking for updates..." is shown, instead of localized message, "更新を確認しています...", wchich is defined in ja/about.cson

2. "Show more" and "Hide" button

"Show more" and "Hide" message are not localized, because I do not know how to handle the click event.

Not tested

I do not test the following message, because I do not know the steps to create the environment that Atom need to update.
