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.
