Update of Search Filter, Homepage, Project & Resource pages

Search Filter --
Improved the Filter so the input fields are now responsive, there are some minor tweaks to be made to the FF version which affects the layout of the date widgets (very minor). In the next pull request I will address the drop down button styling on chrome and FF -- issues overriding the jquery styling.

Homepage --- 
Temporary fix to pull the carousel up 60px to remove gap. The page is inheriting the .container from layout.html which has affected the carousel being full width and pushing it down a little. Will try and fix in future push. Also, changed the background colour to match the original design.

Project & Resource pages -- 
Styled both the pages including add and view.
