[#1260] - Cleanup points

I would like to request that someone take a look at the jsp code in jasperserver.

1. Stylesheets are used and yet alot of jsp files have background colors, colors and pading etc set in the jsp files.
Stylesheets are used so that you dont have to define colors and such in your html code

2. Possible replace ${pageContext.request.contextPath} with <c:url value="" />.

3. Standard for html code. For example:
<script type="text/javascript" src="<c:url value="/cal/calendar-setup.js" />"></script>
<script language="JavaScript" src="<c:url value="/scripts/jasperserver.js" />"></script>
The first line contains type="text/javascript"
The second line contains language="JavaScript"

I know the site works right now but this clean-up would be really nice. Especially point 1. Updating the style of the
site is really hard with alot of styles in the html.

Thanks in advance

(This is realease 1.2.0)
