FIX for issue 1013 and 1020 - also includes fixes to related bugs that were found (not logged)

Fixes issue #1013 - included a new partial view for a non-editable result summary view for the extra percentage table 

Came across the following issues while working on this (also fixed):
- invalid method call if extra percentage was from Penalty Decay setting
- missing UI text if extra percentage was from Penalty Decay setting
- fixed "remove" update of text (translation to points was not being updated after removal)

Added fix to related issue #1020 - rollover of "Show Old Mark Summary" correctly displays old mark summary for penalties/bonuses
