Enhanced the mobile layout
Small fix in the css. Especially with relative sizes.
Added a dynamic path based on the user ID and added the ID parameter.
Since the php needs the user id, the front-end is now able to send the user id.
Small HTML changes:
* Prevent devices to zoom in or out to ensure the best experience
* Censored the title of the second page
Removed unused php encryption utilities
.data is not longer used because of the new user id suffix in the data file names.
