Now display a localized decimal separator.

I've added code so that the decimal separator is localized.
It seems to work on a Mac when switching the regions here in Canada.

Hello,

I am happy to see that someone joined this open source project 😍.

Until now I have been the only developer and I have been a bit careless with respect to repositories, branches and git commit comments.

I can merge your code, no problem, but I am actually now working on a new version.

You can find this in the repository called Calculator in the branch Mac.

I would be happy if you could have a look into this.

In this code, the decimal separator is configurable in the settings and (haven't tested that) the default should correspond to the locale.

This repository should also work better on iPhone, iPad and Mac.

However, there is currently a stupid bug with the processing state, so calculating might not work at the moment, but I plan to fix that soon.

Let me know what you to think.

I tried the new Mac branch and it seems to be missing the gmp/mpfr frameworks.
I can copy those from your other calculator branch and upload the changes to the Mac branch.
