Save, Cancel, Delete buttons should remain visible when scrolling within an entry on mobile

[bicarbon8]

Description:
on Mobile, if you have a few Criteria and are editing an Entry the Save, Cancel and Delete buttons will scroll off the top of the view as you scroll down to edit lower criteria values. Instead, these buttons should stick to the top of the view as you scroll down until you reach the next entry

Changes Needed:

• wrap buttons in new div that sticks to either the top of the entry edit area (right side) or the top of the screen (whichever is lower)
