seems to fixes panel closing issue with fastclick #2761

Adding needsclick to the panel seems to fix the panel not closing issue.
- works on Nexus 4
- with Chrome emulator, tested for iPhone 4 and 5, seems to work
(I noticed that with Chrome emulation of iPhone, I had to **re-type in** the mobile url for it to work, simply refreshing the existing page seems to make everything non-responsive)
