Use a HTML template instead of HTML embeded within python

[Rafał Cieślak]

The point of this but is to clean up the _accomplishment_info(...) funcion. What it does it preparing HTML code for the webkit viewer. All HTML tags are within the code, like this:

html = html + '<b><div style="somestyle">'
html = html + message
html = html + '</div></b><br/><h2> The caption is: <i>'
html = html + caption
html = html + '</i></h2>'

This is not elegant. Editing the HTML code is super difficult, the outcome is not human-readable, and the code of _accomplishment_info(...) is complicated.
The ideal solution would be to use a separate .html template, which would look like this:

<b>
  <div style="somestyle">
    [MESSAGE]
  </div>
</b>
<br/>
<h2> The caption is: <i> [CAPTION] </i> </h2>

Then, _accomplishment_info(...) would load this file, substitute [TAGS] with values (conditionally hiding some of sections), and pass result to webkit.
This way the HTML would be significantly easier to maintain, and so would be _accomplishment_info(...).

There will be:
 <div style="{MESSAGE_DIV_STYLE}">
   {MESSAGE}
 </div>
and when there will be no purpose to show that div:
{MESSAGE_DIV_STYLE} will change into "display:none" ;)

I think it's complete. Just need cleanup&review and then I will propose merging.
