UC-90 Made some changes to update mobile for new FB

This mostly amounted to making sure the newest JS SDK was being loaded and removing some cruft.

Also updated to current style guidelines.

This changeset is moving in the right direction as far as code clarity. This line would be more clear if it were split up into two: 
```javsacript
path[i] = getUrl(...);
i++; // or i +=1
```
