start working on 0.7.x branch

- added FileLog which stores content to the file log
- now Log is only a wrapper - it puts messages to the local buffer and when logsave is used then the buffer is put to FileLog
- new base classes:
  WinixBase (Log, Config*, Synchro*)
  WinixModel : public WinixBase (morm::ModelConnector*, Plugin*)
  WinixSystem : public WinixModel (System*)
  WinixRequest : public WinixSystem (SLog, Cur*)
- singletons: log, slog, plugin are depracated - now references to them are in base classses (WinixBase, WinixModel)
- DbBase,  DbConn and Db are depracated - now we are using Morm project (in WinixModel there is a model_connector pointer)
  each thread will have its own ModelConnector
