EnhanceTrainers - fix

- Fixed positioning of main Trainer Frame
- Used method hooksecurefunc to change blizzard ClassTrainerFrame_Update() function.
I did that to avoid overlapping of the Skills text on the Leatrix BLP scrollbar, if actual scrollbar is not shown.
It was my first experience to hooksecurefunc, so took a lot of time and hope it goes fine!
- Fix for Train All Button enable/disable depending if there is something to train or not.
