Fixes#17. Setting this up on the user side via beamer templates turned
out to be too much of a hassle for users. It seems that the
implementation here works better out of the box compared to what was
originally the case in the metropolis theme, and we don't have to rely
on patching commands as the previous implementation did, so this seems
like a reasonable feature to add back support for.
We thereby also remove the dependency on etoolbox and use of patchcmd throughout
the package, which should mitigate problems that have arisen previously when
beamer has changes its commands.
