ProjectAccess: increase font sizes for project rights

The UI for editing a project's permissions contains a button 'Add
Reference' and a drop down menu 'Add Permission...'. Both UI
elements have their font sizes set to 80%. While this will
probably work for monitors with a rather low display resolution
it causes the text to be uneligible for displays with a higher
resolution as they are way too small.

Fix the issue by removing the extra CSS related to the font size
for both elements.
