Several front end improvements to People Directory portlet

+) Number of Rows: <aui:input type="text" name="rowCount" value="<%=rowCount%>" label=""/>
   Alloy UI already supports label. Why not use that and language.properties?
  
+) The below global variables should not be used. Any other similarly written portlet may override the resourceURL.

<script type="text/javascript">
        var rowCount = parseInt("<%=rowCount%>");
        var portletNamespace = "<portlet:namespace />";
        var resourceUrl = "<portlet:resourceURL />";
</script>

+) Profile.jsp
    Move the styles to css file.

+) View.jsp
    Consolidate style in css file

8) main.js
    use templates for the html code in js
    remove any commented alert statements
