Title: various changes to adding and subtracting decimal word problems

In response to Trello cards (https://trello.com/card/board/known-bugs/4d87e664967a0775082939ab/4ed4e8bc007a3b41a50e6c8a, and card re: data-ensure loops) and Issue #9158 made a number of changes:

- added units to answer form for all but the dollar problems
- removed most of the data-ensure (one problem came up with 21 loops on testing!)
- cleaned up the indenting a bit to make it easier to read
- removed class="solution" from

in hints (not sure why it was there... didn't seem to add functionality)
- removed a couple blank lines
- added names to the problems
