Updates made to the home page. Programmed by Michael.

There have been some updates made to the home page, with more text, the company
logos and a new, better video added. Responsiveness seems to work well but
video is a bit small. (Feature #184)
Resizing of the images. Programmed by Michael.

The Deeson Online logo on the home page has been resized so that it is inline
with the other two logos.
The 'Try it now' button has been added to the home page. Programmed by Michael.

It has also been moved to sit underneath the text so that everything can fit on screen and
there is no need for scrolling. (Feature #184)
Removed padding from the 'Try it now' button. Programmed by Michael.

I have removed some margin padding from the top of the button on the home page so that it
sits in line with the company logos.
Changed the homepage + other minor fixes.
Paired by Geoff and Niklas.

Changed the homepage to fit the mockups even further. The video no longer
appears on -xs devices (group discussion may be needed on this). Other
changes include: Removing tutorial from the navigation bar, fixing a spelling
mistake on the about page and fixing the rules page.
Fixed a small error.
