Added azerbaijani language support

[themisir]

Translated all messages to azerbaijani (my native) language.

@TheMisir there are some conflict, not only in the code level, but also in the usage of azerbaijani.

Could you find someone else that speaks your language to define the default behavior?

Conflict 1

<<<<<<< master
  String suffixFromNow() => 'sonra'; // after
  String lessThanOneMinute(int seconds) => 'bir an'; // a moment
=======
  String suffixFromNow() => 'indidən'; // from now
  String lessThanOneMinute(int seconds) => 'bir dəqiqə'; /// a minute
>>>>>>> master

Conflict 2

bir means 1 (a number). So those texts are same too.

<<<<<<< master
  String aboutAnHour(int minutes) => 'təqribən bir saat';
=======
  String aboutAnHour(int minutes) => 'təxminən 1 saat';
>>>>>>> master

Conflict 3

təqribən and təxminən has same meaning.

<<<<<<< master
  String aboutAMonth(int days) => 'təqribən bir ay';
  String aboutAYear(int year) => 'təqribən bir il';
=======
  String aboutAMonth(int days) => 'təxminən 1 ay';
  String aboutAYear(int year) => 'təxminən 1 il';
>>>>>>> master
