St Louis County modifications

Three features added for the St Louis County version of the site (http://fiscalfocus.stlouisco.com)
<ol>
<li>Dynamic start and end years throughout page based on BudgetLib.startYear and BudgetLib.endYear</li>
<li>On-click event with point style added to dagger to scroll down to footnote anchor.</li>
<li>Null out multiple zero expenditure years instead of just last year. This occurs in St Louis County between October and January every year.</li>
</ol>
All other changes to St Louis County site are specific to our site (mostly cosmetic).
