Partnersite Widget Visual Fixes

[adriancollier]

We have 2 visual changes we need to make within the Widgets that are both bugs raised in #259

1. The scrollbar on the Project Listing widget is sometimes pushed out of the iFrame. While the contents is still scrollable, the bar cannot be seen or clicked on.
   This behavious varies between browsers and systems.
   The suggested solution is to ensure that the Widget always includes a Scrollbar, so that this can be included within the design to ensure that this is not a problem. We have a small side-affect that for Widgets with few projects, we have an unecessary scrollbar, but this is ok.
2. The text on widgets sometimes drops of the end of the iFrame. This is the case for Project Titles and Locations.
   Suggested solution is to use a combination of reducing the font size and wrapping the text onto a lower line.

I think there are still some outstanding CSS rules required for the scroll bar fixes, so re-opening this for now.

Mac OS X does not render scrollbars by default, making this rather awkward to test on OS X.

Scrollbars should be set to Always render before trying to test this on any browser on OS X.
