In the Forums Explore page, the 'Add a Post' header beside the add icon
was split in two lines due to less spacing. This commit fixes this by
giving more spacing to the header, hence resulting in the header to fit
in one line without breaking.

From the Forums Explore page, clicking on a question independent of a
file gave you a critical error, since FileSideView component was being
rendered, and it expected many parameters such as the thumbnail of the
file, whereas in reality the file property of the question was null.

To resolve this, FileSideView component is rendered only if the
particular question has a file associated with it.
