"certificate" configuration variable name

[fcarrega]

Hello, is that normal that the certificate configuration variable is called "certificat" (French for "certificate", whereas all other variables have English based names ?

No it's not :) Someone renamed the variable and make a pull request before I merged a big refactoring PR so I asked him if he could re-pull his changes. Otherwise, I'll do the change.

Hi ! I've made the changes on the SystemPay module and its specs. I'll push this later.

OK no pb, thanks! I you make an alias for the older naming I'll release a minor version, otherwise it will integrated in a new major version as it will not be backward compatible.
