Materialdesign: Remove currency-chf

[PeterShaggyNoble]

Although ₣ is a generic currency symbol for Francs, it's not actually used a symbol for the Swiss Franc - they instead use CHF or Fr.

With the French Franc being long defunct, the only currency I can find (with an admittedly quick search) that that does use the ₣ symbol at all is the Rwandan Franc (RWF) but they primarily use FRw and, even when the Franc symbol is used, it's written as R₣.

I propose, therefore, that currency-chf be renamed as currency-franc.

If no one really uses it do we even need to include it? Sounds like we might as well delete it.

I'd say it's probably safe to remove it, @Templarian, unless you have usage stats that say it should be kept.

It was never officially used to represent the French nor Belgian Franc and, after some more research, it isn't used to represent any current Franc, either.

[Templarian]

I do have stats...

I'm for removing this one too. No point in having currencies that aren't actually used.

Removed!
