Add contact forms and update paths

Add contact forms for Project Bionic project in new contact/ directory.
Update existing contact page to include a default contact form. Move
existing contact page into the new contact/ directory. I also updated
all asset paths to be absolute and made a similar change to the
Gruntfile to minimize compilation errors caused by nested folders.
