LP1928005 Bootstrap Opac: Current charges not aligned on mobile.

This patch removes the classes from the charges table that presents the table in a vertical format.
It wraps the table in a <div> that uses the table-responsive class.

To test add some charges to a patron record.
Bring that patron's account up in the opac and view the charges table in the smallest browser size
possible.
Notice that the table switches to a vertical format and the column names are mis-aligned.

Apply the patch.

View the table again.  The table should now be horizontal with all of the columns correct.
