Support for multicite-commands from biblatex

[frankbits]

The Pull Request #1195 added support for BibLatex commands, but ommited the multicite-commands, because of uncertainty if those would work with the current code.

I've needed to use multicite-commands for my use-case, so I had the problem of autocompletion and "jump to entry" not working anymore.

But I found out, that if I redefine a non-multicite-command to be a multicite-command the biblatex-support seems to function fully.

\def\cite{\cites} % or \autocite(s), \parencite(s), ...

\cite{source1, source2}[1]{source3}. % biblatex-support for all sources

So it seems adding the support for multicite-commands would be the same as adding it for all the other cite-commands, needing no other extra work.

Thanks for the suggestion. It appears you are right, it seems to accidentally work fine. If you want, a pull request to add the multicite commands would be really appreciated! (I guess we should just put 1 required argument by default in LatexRegularCommand.kt, as of course we can't do an arbitrary amount of them).
