LDEV-1597: Added new advanced object ShowResults, which controls whether or not the full results are shown. The user can still see their votes in export portfolio and if they return to the voting screen.
LDEV-1255: Moving the code for stopping jsps caching to a new custom tag, so that it can be applied consistently across all pages. Moved the utf-8 statements to the same tag so we don't have to remember to put them in all pages.
