Fixed data parse issue (issues https://github.com/Iceloof/GoogleNews/issues/119).
`.total_count()` is not working with `.search()` anymore.

While encoding the query/key, replacing space with + was responsible for two main problems

- Users were not able to use phrases properly (issues https://github.com/Iceloof/GoogleNews/issues/109 and https://github.com/Iceloof/GoogleNews/issues/107).
- Users were not able to use additional techniques to refine their searches (issue https://github.com/Iceloof/GoogleNews/issues/66)

This simple change resolves both issues and works for both search and get_news functions.

- Fixed date issue

- Allow period in get_news()
- Enable/disable exception

- Update Google code changes

- fix search problem. (https://github.com/Iceloof/GoogleNews/pull/95)
