* Completely checked and transtaled Vietnamese
I spent 1 week (few hours/day) to check every single line in **bundle** and translate:
- Make `bundle_vi.properties` has same lines as original bundle file `bundle.properties`.
- Retranslate some old strings/words which:
+ From very old versions.
+ Mis-translated.
+ Multiple meanings in Vietnamese.
+ Some sentences were add/removed.
- Translate new strings from very last commit (7f30cd8703)
* Small fix
First letter.
