Add japanese l10n

[yamamoto-ryuzo]

Currently, we are also asking the Japanese QGIS user group for any translation corrections, including wording and so on. We are planning to revise the translation to make it more suitable for use. Thank you very much.

Hello @yamamoto-ryuzoI

I worked on using transifex for translations: #35 So translations could be done here: https://www.transifex.com/camptocamp/QGIS-SpreadSheetLayers

I invited you as japanese language coordinator for this project. After accepting the invitation, you should be able to:

• Invite people to a language in a team
• Approve/deny join requests for a language in a team
• Change the user roles of members in a language of a team
• Start a team discussion in a particular language
• Review and Proofread translations in a specific language
• Submit translations in a specific language

Hope it would be easier for every one like this.

Note that there is two resources:

• Spreadsheet for the plugin itself (already translated)
• help for the content under help button in the dialog window.
