GPII-669: Fix positioning of Save button in PCP

After a long discussion in JIRA: http://issues.gpii.net/browse/GPII-669 in which me and Dana were striving to make the Save in PCP as visible as possible in both on and off contrast, the closest we got to is this.

The pull contains proper positioning of the button (now there's no empty space between the adjusters), there are some naming fixes as well.
