Beamer Template: \footfullcite extends into LU logo

[valentinaschueller]

Thanks for providing these templates! For presentations in Beamer, the horizontal width of footnotes is too large and they can extend into the LU logo. I noticed this when using \footfullcite, which can produce long footnotes for references, see screenshot:

Good that you found this! If you are inclined to create a PR, contributions are welcome?

@StefanHost Do you want to take a look at this?

This should work to fix this and simultaneously handle the use of a left-hand logo by centering and reducing the page-size for the footer:

\setbeamertemplate{footnote}{%
  \begin{center}
    \begin{minipage}{0.875\textwidth}
      \scriptsize
      \parindent1em\noindent%
      \insertfootnotetext\par%
      \raggedright%
    \end{minipage}
  \end{center}
}%
% \renewcommand{\footnoterule}{}

The last line can be used to remove the footnote ruler, which I personally don't like.

Looks good. PR welcome!
