Update fusion.js

Added route "/fusion-no-appcache" which uses localStorage instead appcache. This is super cool but doesn't work :) localStorage size limit is 5 MB :'(
Update smart.json
Update README.md
Merged from master
Now working in devel mode: in regular browser (cordova serve)
Merge pull request #3 from usefulio/devel-pk

Now it works in devel mode too but only in regular browser. Also, added new route `/fusion-cordova` which uses localStorage instead appcache for storing app files.
