    invoice, easy-invoice.scm: %discount from html-table to string
    
    Old code would nest a small single-row, 2-column html-table within the
    entry-list html-table to display discount percentage and '%'. This is
    an overkill and causes alignment issues. Display a string instead.

    TR: Price Column shown in commodity SCU
    
    xaccSplitGetSharePrice will typically return a gnc-numeric (or scm
    rational) value. This leads to the TR showing a price of, eg. $22 +
    12228521/25349850 which is not ideal. This commit will modify the
    share price to round the exact rational to an inexact decimal
    according to the account share price currency SCU. If the SCU is less
    than 10000, increase the precision by 2 significant digits.

    This fixes a numerical-overflow error identified in bug 792800. It is
    related to negative-stock-balance situation.
