Google Code-in

For this task, we'd like you to implement fixes for four recent issues reported about the site. These are all little issues with the display of the user interface which detract from the overall cleanliness or usability of the design. The issues to fix are:

• BB-154 - The search button in the navigation bar is not aligned with the search input field
• BB-152 - Navigation bar buttons stay highlighted after clicking on them a second time
• BB-148: Weight not displayed in entity create revision diff
• BB-149: Disambiguations should be displayed in edition lists

Each of these bugs should take between 30 minutes and an hour to fix, once the site is set up and running. You should be able to use the sandbox webservice (as in the default site configuration) for the site to access data.
