Fixed various issues reported by resharper. Added move constructors/move assignment operators to various classes. Exceptions cleanups. Removed unused code. Removed copy constructors/copy assignments from various noncopyable classes. (CH-318).
Changed the default task versioning to be independent to CH version (as data model won't change as often as CH version numbers). The version was set to 1 and there is no migration provided as this is the alpha version. (CH-127).
Added new string class (TString) along with exportable containers for them, that will help solving problem of non-exportable std::wstring (and lack of CString at some places in code).
