Lesson41 -- Dependency Injection with Spring Framework

0) added 'PhonebookWeb-context.xml' to find all Spring-annotations
1) '@Component'-s -> all servlets + validators ; '@Repository'-s -> all DAO-classes ;
'@Service'-s -> all service-classes.
2) In JSP pages -> instances of services get from spring-context
3) Adding into web.xml file context-parameters refers to Spring-context

4) I don't know why, but my old version of 'server' and 'webapp' modules weren't downloaded into GitHub --> I do it now. (But I think, it was because of '.gitignore' file).

5) Deleted files 'ConfigurationListener' and 'TestServlet' -> I have no need to use them anymore. And, I deleted 'config.properties' file.
