Liberation from softwarerero:accounts-t9n

From now:

1) to add any i18n package manually
```$ meteor add  softwarerero:accounts-t9n```

2) to set wrapper function
```
AccountsTemplates.translate = (string) ->
  T9n.get(string, markIfMissing=false)
```

PS I solved the problem of inline errors

```
en =
  "Minimum required length: ": "Minimum required length: " 
```

```
ru =
  "Minimum required length: ": "Минимальное кол-во символов: "
```
