Changed the header

Changed the look of the header to more accurately reflect what will be
there, will most likely change the text later to something like "Welcome
*name* choose a game" after cookies are working!

was merged into "introAndSelectAGameStyles.css"
the styling was just way to minimal to justify it having its own
