Add KDEVPLATFORMSHELL_EXPORT annotations to ProblemStoreNode classes.
Summary:
Without marking these classes as exported, dynamic_cast<>'s on them fail. This was causing test_problemstore to fail on FreeBSD.
This problem can be made visible if you move ProblemStoreNode constructor into a .cpp belonging to KDevPlatformShell library. The test_problemstore would fail to link then, due to unresolved references to "typeinfo".
Test Plan: test_problemstore now passes on FreeBSD
