Catlinks at the bottom of all the content and fix the overlapped footer

[ivanhercaz]

Trying to solve #9, I think one solution might be to use this little snippet (first commit):

#catlinks {
	clear: right;
}

I added at the bottom of the stylesheet but if you think it should be in another place, you can replace it without problems (my PRs allow edits from maintainers).

But, in the another hand, I detect one problem with the footer when it is in a mobile device. This is the current result (and error):

And this is how it looks after disable the bottom: 0 in .smwofootergrid.container, that I deleted in the second commit of this PR:

@kghbln, could we test in smw.o? I hope it works and solved both issues.

I guess this is about fixing one issue and adding another one. If I remove this the display on pages like this one is borked.

Moreover I do not see this behaviour you wanted to address, admittedly only by narrowing the browser on a desctop pc.

Can you at least scroll?
