Make sidebar optional for multipage CVs

[fdgonthier]

I've followed the instructions in other issues about making the CV in multiple pages but I think that the sidebar is superfluous in the second page. I would like to get rid of it while keeping the LimeCV layout.

I probably could figure out how to do it, which might involve overriding cvMainContent environment for the second page but my skills in LaTeX are pretty limited so it's likely to take a little while.

The sidebar is good for increasing the density of the first page, but becomes empty in the second and next pages.

Just before the 2nd page cvMainContent, I have added this.

\setlength\cvMainWidth{\paperwidth-4\cvMargin}

This partially works. I'm on the right track. I'm pretty sure I will able to further tweak that to my satisfaction.

I'm leaving this open in case it attracts further comments.
