[Feature Request] Support for custom company URL

[Az8th]

Hello,

I kindly ask for the addition of a "custom company URL" field in order to add support for self-hosted Azure DevOps Server
Leave it empty would use the default "https://dev.azure.com/" URL

Is it possible ?

Thanks and have a nice day !

I proposed a merge request (#4) adding this feature, @Buzzet could you review it please ?
