Widget updates

- Greenhouse "public folder fix" (I had to modify the files widget to use the ProfileService to pull the user profile data in before being able to pass the creator ID to the file grid)

- Community Files fix (the dropdown box for the community files widget only listed the communities specified via the default page size - I now set this to the maximum number to retrieve all communities).

- CSS dialogue box fixes (tidied the header and padding of dialogue boxes to look consistent across all samples)

- Consolidated the files grid and community files grid (they looked slightly different)

- FilesView changes: buttons that might confuse users are automatically hidden (e.g. when selecting "public files", the "Upload File" button is hidden since, by default, uploading a file will place it into "My Files" (unless the user specifies otherwise)

- Removed redundant calls to console.log()
