Add padding settings to site title

[Jeremy Hopkins]

Need to add padding options for #coursetitle and to set defaults to work on new install.

I did this fine tuning having modified #coursetitle in custom CSS styles. It took some iterations to align the title with the site logo. However I didn't use padding - it'd have increased the height of the heading that I wanted to keep narrow. Applied 'position' style instead.

I just fixed this under a duploicate issue #255

There is now a padding setting under the "layout" section for this and the default is 0px.
