Allow setting the charset globally, not only on per-mount basis
Hi! In my setup, I use a script that manages the sources dynamically, creating, starting and stopping mount points by user request. The icecast config is static, and all the sources share the same login/password. So no need to declare mount points in icecast.xml in that case.
Unfortunately, IceCast uses the charset ISO8859-1 by default, and the only way to override it is declare mount point for each single source and specify <charset>UTF-8</charset> for each. This is extremely inconvenient.
I tried the following simple patch and seems to work. It allows to set the charset at the upper level so it takes effect for every mount point that doesn't explicitly override the value. If no charset is set at all, the default ISO8859-1 is used as the last resort.
Could you please merge it?
