Some UI fixes

Hello Alex and other webcoinx developers, here are some small changes:
1. Make the github ribbon not cover the create button, also change the ribbon to pure-css
2. Verified it works on IE10, sencha_touch used addEventListener so I had to remove its use in the IE version
sencha_touch is old, it might probably need to be updated to the 2.0 series to make it work on WIndows phones.
