Bugfixes

Hello,

I implemented a base class in my project that overrides findViewById method as well. It then crashed in SidemenuActivity.onCreate method when you call it rather than calling super.findViewById.

I have changed it in all three activities but there are more such calls in them. You know the code better and should also fix these. Make sure you do not call overridden findViewById unintentionally.

P.S. Maximum scroll scale limit of 1 is bad. I changed it to 2 because that allows user to hide side menu entirely when front content is shown.
