Adding in mobile support for module. This will make the logo display only for screens larger than 767px.

Update code comments, remove whitespace, and change the variable names to our shorter names, passed in from the module.

Shorten the variable names passed, since they are scoped within our logo_watermark in Drupal.settings.

Conflicts:

Cast variable to an int. jQuery fadeTo will convert any non recognized string (i.e. "fast", "slow") to default to 400ms. Drupal is saving our values as a string to the database, so any value entered is basically being ignored. This gets around the issue for now until a cleaner way is built.

Replace placeholder text with Drupal.settings variables, change the position from 105 to 35 (which represents 35% scroll before it fires).
