fixed for localization issue

[YoshihideShirai]

Hi, @Mogztter .

I found a issue that relate a localization .
Localizations didn't work except config's titles or descriptions.

vscode-nls-dev has procedure which is following...

1. Search nls.loadMessageBundle() from js files
2. Create xxx.nls.json by js file name which is found in "1.".
3. Create *.nls.[jp/fr].json from a i18n directory and "2.".

In current master branch, only i18n.ts has nls.loadMessageBundle().
I think that it is a bad implementation.

Can you check it?
And, please translate English message in i18n/fra/src/security.i18n.json.

I think you are right, my goal was to load and configure nls.config({ messageFormat: nls.MessageFormat.file })() only once but indeed nls.rewriteLocalizeCalls rewrites calls per JavaScript file.

I wonder how it's gonna work if we produce a single JavaScript file: #506.

Anyway, I will fetch your branch locally and update the French/English localization.
