* Gofmt friendly
Keeping Go source code in line with what they preconize
* Golint Friendly Next
So I have made some variables unexported
Added comments in every function that I know what it does
Removed some deprecated stuff that I was sure of
Added a comment on possible deprecated methods "Is it deprecated?"
Changed some variable/method name according to golint recommendations
* Update filelist.go
This consolidates the places where a default language has to be set.
- Removed import of the 'userService' package into the 'languages' util
package
This was required to prevent a cyclic import between the two packages.
- Added a 'UserRetriever' interface to read the language setting of users
inside the 'languages' package
- Fixed an error in the spanish and chinese translation file
- Refactored reading the translation files
Instead of ignoring errors in the non-default language files
the error will now be returned and the remaining files will
not be loaded.
- Added a unit test to check if all translation files are valid
- Added an i18n config to specify the translations dir and the
default language
