[mureev]

1. wrong start position of TabBarRow in CustomTabBar original issue https://github.com/boctor/idev-recipes/issues/4
2. Fast changing tabs glow bug Than tabs canes really fast - glow jumps with delayed sequences. Fix this - stop prev timer than tabs start changing fast...
3. Not called viewWillAppear:/viewDidAppear:/ etc original issue https://github.com/boctor/idev-recipes/issues/5
4. Tapping an already selected tab bar item does not pop the selected view controller's navigation controller (if any) to the root VC. original issue https://github.com/boctor/idev-recipes/issues/5
5. Add init method without xib, update TabBar protocol for different images and glow for tabs, add glow block animation
