Removed, interface "Topic" has this info implemented.

This operation helps to set Course type as free or paid. I added "enum"
Course::types where possible Course types are listed.
Also created "enum" Problem::types to take care of possible control
solution types.

No need to have it in interface "Topic", I moved it to interface "Problem"

Fixed. Now Topic::getProblemSolutionList() returns str_Vector - template
that stores strings with problem solutions.
