Version update, updated dist, readme spelling fixes.

1. There were 2 minor spelling mistakes in the readme, which have been corrected.
2. The current version is listed as 1.1.5, but the dist files are showing an older(1.1.0) version, so updated the respective bower and grunt files.
3. I'm not too familiar with grunt/bower, but i have attempted to update the dist/js files as well by doing a
    
    `grunt build`
    
    however these js files have a lot of diffs, but the tests do pass. Still i'm unsure if everything is correct.
